rocky 9 lh comps roughly matched centos stream 9. it was missing rhel
specific packages, and sometimes made diff/merges difficult. we added
them back, but the difference here is we are taking advantage of stream
10's "rhel_only" kind of concept, assuming this does not mess up
diff/merges.

* Start an 8.9 (may convert to .xml.in to match upstream?)
* Branch lh to 9.2 (there was a couple week gap in activity, assume
  this is the case)
* Update lh comps in general
