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.
