Fixes a path where something somehow went wrong with #257

Okay, something is wrong here. This workflow should not have been run here.

Using run_id may be wrong: https://docs.github.com/en/actions/learn-github-actions/contexts

github.run_id	string	A unique number for each workflow run within a repository. This number does not change if you re-run the workflow run.

Edit: Tested and now understand this. It returns the number THIS workflow was run, not ANY workflow. I thought it was combined, but it is for this thing here:

Okay, I know why the workflow was triggered, the create event runs each time a ref is created, including creating new branches. It works for the purpose as it gets triggered when the repository is created and thus the master ref is created. When cloning repositories this should not be a problem but we should add a check that it is the default branch. And I think we can hardcode it to master since that seems to be fixed by the template use action.

Confirmed to be working as expected, even when cloning all branches.
