Define git_service config getter for Github actions

[kdarkhan]

This is my attempt at fixing the issue google/mdbook-i18n-helpers#173.

I am not very familiar with this codebase but I think it might fix the issue.

My Github workflows implements an unusual technique for codecov uploads which I described in this thread.

It used to work in codecov-action v3 and stopped working in v4. The error I am getting is Commit creating failed: ["Service not found: none"].

I suspect this is due to missing implementation of _get_git_service in github_actions.py.

I just discovered codecov/feedback#263

Based on codecov/feedback#263 (comment), my PR might fix the issue.

Ok, I see now that is not that simple. The service could be either github or github_enterprise.

If my approach is wrong, it would be nice to expose git-service param in the codecov-action.

@drazisil-codecov could this PR fix the issue that you mentioned in this comment?

It might, but as you observed , that doesn't help github_enterprise. However, "enterprise" in this context refers to self-hosted, or a URL that isn't github.com. I think that if it could be aware of if a URL was also passed, that should be good.

Also tests, please , if possible.

I'll refer to @thomasrockhu-codecov since I don't really touch the action code that much.

Thanks for response, @drazisil-codecov.

I will wait for confirmation from @thomasrockhu-codecov on the approach. If this approach is correct I can add tests as well. Did not want to invest too much work into this since I wasn't sure if this is the right fix.

Based on codecov/feedback#263 (comment), this is not needed. The fix will be done differently.
