Fix links to moved content, and add front matter
to new files.

Continued work on creating_merge_requests.md
by adding section for important basic details
on the workflow, and adding/removing links
and sections as necessary. Drastically simplifies
documentation for MRs.

Update links in various pages to updated locations

Remove all duplicated information, consolidate it all in
tables, and update links. First pass.

Split docs into an index, a create MR doc, and a review MR
doc. [ci skip]

Moved MR doc features around, and updated links
to those sections

Fix time-dependent test failure in release_block_spec.js

Closes #35019

See merge request gitlab-org/gitlab!19194

This test was using timeago.js to show amount of time elapsed since the
release date. Since timeago.js uses Date() to determine the current
timestamp, we can just mock that value to ensure consistent results.

Closes https://gitlab.com/gitlab-org/gitlab/issues/35019
