(SIMP-10633) Update standardized assets (#164)

This commit rolls up various improvements to the GHA tag & release
workflows, particularly:

  * Tagged releases build a matrix of RPMs: (EL8 *and* EL7)
  * Tagged release logic supports pre/post-release tag formats
  * New arguments in `release_rpms.yml`: `path_to_build` and `verbose`
  * Ensure jobs run on `ubuntu-latest`
  * Fixes for variable edge cases and inter-job dependencies

The patch enforces a standardized asset baseline using simp/puppetsync,
and may apply other updates to ensure conformity.
