[9.x] Close illuminate pull-requests.

[lucasmichot]

#39318 and #40733 have introduced .github/workflows folders and .gitattributes files per sub-repository.

The goal is to auto-close any open PR in one of the associated illuminate repositories.

I feel there is something simpler with less maintenance could be possible here.

Each Github action comes for free with the gh cli, so we can use it.
In the script file, the repositories for which PR should be close have a read-only topic, but this could be anything else.
Of course a GH_TOKEN needs to be set with write access to the illuminate organisation

The script would run every hour, which is more than enough

Side note, Github also promotes the org wide setting public repository called .github:
https://docs.github.com/en/communities/setting-up-your-project-for-healthy-contributions/creating-a-default-community-health-file

You could add the script and the workflow fiels in this repository, and you could skip setting the GH_TOKEN token; I also feel this would make more sense:

• https://github.com/illuminate/.github/.github/workflows/close-pull-requests.yml
• https://github.com/illuminate/.github/bin/close-pull-requests.sh

And you can also add a bunch of community health files and a global readme, which is great

cf. #40766

It could also be nice to have PR locked too here

I think this is a good idea @lucasmichot but I believe having the separate files is still better to have. With the new way of doing things, people could maybe be waiting an hour on that feedback while right now they'd get the message instantly. I know we could adjust the cron to run every minute or so but to be honest I think having the separate action files is more easily to maintain than a single bash script (I know!). I feel like a dedicated action script per Illuminate repo makes sense.

Moving the action/script to a separate .github repo isn't something we should do I think as that detaches it too much from its purpose.

Still want to thank you for your effort here!
