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.

Blank

Blank()

Validates if the given input is a blank value (null, zeros, empty strings or empty arrays, recursively).

We recommend you to check Comparing empty values for more details.

v::blank()->assert(' ');
// Validation passes successfully

v::blank()->assert(0);
// Validation passes successfully

v::blank()->assert(false);
// Validation passes successfully

v::blank()->assert(['', ' ', '0.0', []]);
// Validation passes successfully

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

It's similar to Falsy, but way stricter.
