We want to release version 3.0 as fresh as possible, without having to
maintain backward compatibility with the previous versions. Because that
version will be on for some time, we decided it will be best to support
only PHP version 8.5 or higher.

There are a few cases in which we want to validate the object as a
whole, and that validation could be attached to the class as a PHP
attribute. This commit enables that capability and changes a few rules
to be class attributes.
With this change, any rule can be used as a PHP attribute. I have wanted
to implement this feature for a while, as it allows you to bind the
validation to a specific property and just validate the object
afterwards.
I'm not a native English speaker, and the same goes for many
contributors from this library. Because of that, some messages just
don't sound very good, so I updated a lot of them.
Besides the interface's name, everything already calls this type "Rule",
not "Validatable." This commit puts a stone on it and renames the
interface for better naming.
So far, I haven't seen any real case for that, but it's not like I have
a strong case for not allowing that, I just want to keep the code clean.

There are a few "problems" with the current engine:
- Allowing each rule to execute assert() and check() means duplication
in some cases.
- Because we use exceptions to assert/check, we can only invert a
validation (with Not) if there are errors. That means that we have
limited granularity control.
- There is a lot of logic in the exceptions. That means that even after
it throws an exception, something could still happen. We're stable on
that front, but I want to simplify them. Besides, debugging exception
code is painful because the stack trace does not go beyond the
exception.
Apart from that, there are many limitations with templating, and working
that out in the current implementation makes it much harder.
These changes will improve the library in many aspects, but they will
also change the behavior and break backward compatibility. However,
that's a price I'm willing to pay for the improvements we'll have.

Creating a specific exception for each rule adds a painful overhead. If
you want to make a custom message for your rule, you will need to create
an exception and then register that exception namespace to be able to
use it—all that is just for customizing the message of your rule.
Having different namespaces also implies that you need to fetch the
exception of the rule from another directory to change it. As Uncle Bob
said, "Classes that change together belong together. Classes that are
not reused together should not be grouped."
This commit will drastically change this library, moving all the
templates from the exceptions to the rules. Consequently, the Factory
becomes much simpler, and the library gets a bit smaller, too.

Currently, we convert the properties of a rule into parameters and pass
them to the exceptions. That complicates things for a few reasons:
1. The exception knows too much: there's a lot of information in an
object, and the exception would only need a few parameters to work
correctly.
2. Any variable change becomes a backward compatibility break: if we
change the name of the variable type in a rule, even if it's a
private one, we may need to change the template, which is a backward
compatibility break.
3. The factory is bloated because of introspection tricks: it reads the
properties from the class, even from the parent, and then passes it
to the exception.
Of course, that means we introduce another method to `Validatable`, but
in most cases, extending `AbstractRule` is enough to create a new rule.

That will make it clear that we should not overwrite some properties.
Because of this change, I've made a few refactorings here and there.
It's nice to see that I've spotted some issues just because I was
setting some properties as `readonly`.
There are a few properties that I would like to make read-only, but to
do that I'd need to refactor a lot of code, so for now, I'm keeping it
as is.

This change will bring many breaking changes. The good thing is that we
can finally use more modern resources available in PHP.
I can imagine that's not a popular change since it will bring many
breaking changes to users, but we shouldn't be stuck in time because of
that. Using some of those features will make it easier to contribute to
the project. At least, I hope so.
There are still some useless doc-blocks, and we're not using "readonly"
properties when we could. I aim to send those changes soon.

The "Call" validator, the "assert()" and "check()" methods, define a
custom error handler so it can handle the validation in case of a PHP
error. However, it does not restor the previous error handler when the
validation fails.

According to the official documentation [1] the correct way of writing
the "inheritDoc" tag is with the uppercase "D".

The callable defined to the "Call" rule may also throw an exception and
as we don't want to have errors nor exceptions that are not part of the
Validation during the validation of inputs it just makes sense to
intercept any instance of Throwable.
This change was initially thought of because in Travis the version 7.4
of PHP was throwing "Error" instead of triggering PHP errors which made
the tests fail.

This commit make sure that when the callable is executed by the "Call"
rule and PHP triggers an error, the user does not have to deal with it,
and instead the rule will throw "CallException".
Because of the many changes that were made, it didn't make sense to keep
the class "Call" extending the "AbstractRelated" class.
One thing that is a bit problematic with this rule - and with other
rules as well - is that Validation only knows details of a validation
when it fails, because of that we cannot invert the validations that
passed, meaning that the "Not" rule cannot give the proper response to
a validation that passed. This is a know issue that can only be fixed
is we provide a way for Validation do have more granularity control.
