This turned out to be not so bad, please see attached.

Here's the way it works:

- If you are viewing release notes in documentation prior to 9.4, do nothing
- If you are viewing the release notes in documentation for 9.4 and
above and you are viewing the release notes in your version (e.g. 9.4.8
in 9.4), do nothing
- If you are viewing the release notes in docs for 9.4+ and you are
viewing a "mismatched" version (e.g. /docs/10/release-9-6-4.html),
permanent redirect (301) to the proper version (e.g.
/docs/9.6/release-6-4.html)

It accounts for version numbering changes and all the fun

Notes:

- Tested in multiple scenarios, also dealing with different versioning
number permutations as well (e.g. release-10.html, release-10-1.html,
release-9-6.html, release-9-6-1.html)
- Tested with current. I did not test with devel as I do not have
"devel" docs set up on my local. However, I am going to work on setting
that up
- Given docs on the site go back to 7.2, there is a stop that says if
you are viewing a release note older than 7.2, then view the releases
notes in 7.2

This can be pushed independently of the previous patch as it redirects
users to existing documentation.

Feedback welcome. Thanks,

Jonathan
