regarding the last point, i'm happy to assume responsibility for updating and running the action when a new repo is created, but i'm not sure of the best way of being notified. i just enabled this

although i didn't get an email when i created a couple test repos just now. @gtdang @younesStrittmatter can either of you try creating a dummy repo? alternatively, do you have any better ideas for streamlining the process of updating and running the action when a new repo is created? i haven't (at least yet) found a satisfactory way to automate. @gtdang, what did you mean by creating another action?

I was curious if there was way to have an action that upon detection of a new repo, it will automatically update the label sync action with the new repository name. It will kind of behave like a dependabot and create a new PR with the updated label sync gh action yml.

I think we can merge your existing PR and create a new issue for the last point as a nice to have. For now the manual method will suffice? Actually the documentation part should be done. But the GH action would be a Priority 3.
