Add region sections to format-links precommit (#14818)

* Add region sections to format-links precommit

The precommit was moving links inside the `site-region` sections to the
end of the document, causing them to break. This alters that behavior
to mimic links that are in tabs or `programming-lang` sections.

* Updating

* remove whitespace

* backing out formatting changes
