Related to RHIDP-1720 - see recent news about using a release-1.3 branch instead of a 1.3.x branch.

• any changes in the plugins' main branch that we need to be in the release-1.3 branch should be cherrypicked there OR if you want EVERYTHING in your plugin(s) in the main branch to land in 1.3, then whole plugins could be copied over (from the current latest version); then main can be incremented to the next y-stream version (eg., copy plugins foo, foo-common and foo-backend 1.4.6 to release-1.3, then bump them to 1.5.0 in main
  • confirm that we're ready to do this at some point tomorrow after the Pgm call
  • https://github.com/janus-idp/backstage-showcase/pulls?q=is%3Apr+is%3Aopen+1.3.x should be empty (not 17 open PRs) DONE
  • https://github.com/janus-idp/backstage-plugins/pulls?q=is%3Apr+is%3Aopen+1.3.x should be empty (not 17 open PRs) DONE

• midstream updates:
  • the tagRelease script which handles branch creation and tagging will be updated to the new convention - 1.3 and 1.next branches
  • midstream sync scripts in gitlab will be pointed at the new branches - 1.3 and 1.next branches

• the 1.3.x branches in all the repos will be copied to release-1.3 - this includes the repos below
  • force push commits from the current 1.3.x branch into release-1.3; check branch protection rules and copy 1.*.x to release-1.*; make existing 1.3.x branch readonly
