ci: Repo stats workflow

[luarss]

Resolves #5667

[github-actions[bot]]

clang-tidy review says "All clean, LGTM! :+1:"

Where does the data get stored?

[luarss]

They get stored in the repo-stats branch.

Example: https://github.com/luarss/awesome-conference-dates/tree/repo-stats/luarss/awesome-conference-dates We can also specify the folder to store this in the target branch, but since I did not they just used author/repo

[maliberty]

There is no such branch today - does the action create one? Can it be configured to store the data in a different repo?

Yes you don’t have to manually create the branch. It seems also that directing to a data repo is possible, but the token needs to be able to given sufficient permissions
