Managed PR profile per PR

[GeckoEidechse]

Instead of having one profile for all PRs, we should have profiles PR to allow for testing multiple in succession more easily.

Also, include the PR number in the profile name so it's easy to tell which PR a profile is from.

Also write the current commit hash into a file in that profile folder so that we can check if the local copy is outdated and then update it accordingly.

Will require better profile support as a prerequisite.

Also, only really makes sense for mods PRs atm.

Additionally also check if any PRs have been merged/closed and prompt to delete these profiles again.
