[ADP-3237] automate release candidate branching (#4371)

- [x] Remove unused rc-latest GH workflow
- [x] Add a `release-candidate.sh` script that
       - Search for last green CI-1 build on master
- Forks a branch named `release-candidate/v\<YYYY-MM-DD\>` with today's
date
       - Add release tweaks (version bumps)
       - Pushes the new branch to origin
- [x] Create a release-candidate fork github workflow that forks every
day at 20:00 and run the `release-candidate.sh` script
- [x] Remove the release table in `README.md` as difficult to keep
update. The link to the releases is preserved.
