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.

# TrueVal
- `TrueVal()`
Validates if a value is considered as `true`.
```php
v::trueVal()->assert(true);
// Validation passes successfully
v::trueVal()->assert(1);
// Validation passes successfully
v::trueVal()->assert('1');
// Validation passes successfully
v::trueVal()->assert('true');
// Validation passes successfully
v::trueVal()->assert('on');
// Validation passes successfully
v::trueVal()->assert('yes');
// Validation passes successfully
v::trueVal()->assert('0.5');
// → "0.5" must evaluate to `true`
v::trueVal()->assert('2');
// → "2" must evaluate to `true`
```
