[Monorepo] PR "move" and wrapping up

[pkra]

To wrap up the monorepo move, please complete the following:

• review PRs (see link list below)
  • close PRs that were "moved" correctly
  • handle PRs from forks (which could not be "moved" the same way)
    • either alert authors to make new PRs to on the ARIA repository and close the PR
    • or (to maintain a useful diff) create a branch (e.g., "old_main") and change those PRs to target that branch
• merge "closing" PR Editorial: Move this spec to ARIA monorepo #237
