Stop using v1 and v1.x tags for Docker images

[yurishkuro]

Which problem is this PR solving?

• We used to publish Docker tags like "1" and "1.60", which were aliases to the most recent fully-qualified version. This is a bad practice, nobody should be depending on those aliases since they can introduce unexpected changes to production
• Part of [jaeger-v2] Release process #5889

Description of the changes

• Only apply fully qualified vX.Y.Z tag
• Do not generate any tags for runs not on main branch and not on numbered release
• Rename poorly named internal action actions/block-pr-not-on-main to actions/block-pr-from-main-branch
• Remove name from many workflow steps as it's redundant
• Add "::group::" boundaries to log output to make it easier to navigate on github

How was this change tested?

• CI
