Also small improvements:

• running a YAML formatter over all workflow files to fix formatting
• Sync labels with file
• Naming improvements

How Has This Been Tested?

• To be seen in future workflow runs

By the way, @igorpecovnik I'm trying to understand the "rebase.yml" workflow for doing a rebase command via comment. Is this any different than the button "Update branch" on the bottom of a PR?
If it's the same, maybe we don't need this workflow? It has only been used 5 times in 4,047 runs 😅 https://github.com/armbian/build/actions/workflows/rebase.yml?query=is%3Asuccess

maybe we don't need this workflow?

This command is here before GH provided this option and we don't need / use it anymore. Yes, safe to remove it.
