Using Release Candidate branches for all work

[blackfalcon]

TBD...

initial ideas and questions:

1. What is an appropriate release time gap?
2. Immediate bug releases can be instantly released and the RC branch rebased on main
3. List ALL Release Candidate PRs on the Kanban board
4. Start using beta releases https://github.com/semantic-release/semantic-release/blob/master/docs/recipes/release-workflow/pre-releases.md

I have received feedback that releasing so often causes frustration with users. There is nothing wrong with building a release candidate that we have completely tested and ensure compatibility across all components.
