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.

IterableVal

IterableVal()

Validates whether the input is an iterable value, in other words, if you can iterate over it with the foreach language construct.

v::iterableVal()->assert([]);
// Validation passes successfully

v::iterableVal()->assert(new ArrayObject());
// Validation passes successfully

v::iterableVal()->assert(new stdClass());
// Validation passes successfully

v::iterableVal()->assert('string');
// → "string" must be an iterable value

Note

This validator doesn't behave as PHP's is_iterable() function because it considers that you can iterate over any object.
