Docs/releases: Finalize 4.22/4.22.01 release notes

Now that the 4.22 release tag has been added to git, update the release
notes with the final statistics and wording.

We also decided to add a fix submitted immediately after the 4.22
release was tagged into the release package and do a point release.

This also adds an expected date for the next release

+### 4.22.01 release
+
+The week between tagging a release and announcing it publicly is used
+to test the tagged version and make sure everything is working as we
+expect. This is done instead of freezing the tree and doing release
+candidates before the release.

+For the 4.22 release cycle we found an uninitialized variable error on
