RC pipleline

Problem:
EVEREST-428

Everest needs a workflow for building release branches.

Solution:
Create a manually triggering workflow. It would accept the version we want to create the RC for and would create the release-*.*.* branches in the backend, cli, frontend and catalog repos. It will update tags in the deployment scripts (so no manual intervention needed to run it from the rc-branch), build and push the new image to the registry.

1. Do we need to duplicate the required checks in the RC pipeline? I suggested to add this requirement

Required checks should pass before triggering the job

but on the second thought it's gonna be hard to maintain the duplication and it doesn't bring that much value since we have that checks running on every push to main anyway

The pipeline should be triggered on any new commit across backend and frontend repos to rebuild the release image

Once we agreed on this workflow, I'm gonna add to the FE repo the simplified version of this workflow which is gonna be triggered by any commit to the release-x.x.x branch and will rebuild the rc-image.

Required checks should pass before triggering the job

We can skip this and be sure that pipelines are passing before triggering the job
