Alexandre Gomes Gaigalas bd48bdcda4 Lint Changelog format in validator docs
Introduces a Markdown linter for checking the Changelog format.

"See Also" was transformed into a section to make it easier to
handle it with the `Content` class. The "Related" linter was
simplified to reflect that change too.

An additional "alignment" parameter was added to markdown table
generators, allowing the padding and headers to be explicitly
marked with a specific left (-1), middle (0) or right(1)
alignment.

Existing files were fixed using the `fix` option after the
changes.

# Base
- `Base(int $base)`
- `Base(int $base, string $chars)`
Validate numbers in any base, even with non regular bases.
```php
v::base(2)->assert('011010001');
// Validation passes successfully
v::base(3)->assert('0120122001');
// Validation passes successfully
v::base(8)->assert('01234567520');
// Validation passes successfully
v::base(16)->assert('012a34f5675c20d');
// Validation passes successfully
v::base(2)->assert('0120122001');
// → "0120122001" must be a number in base 2
```
