Workflow failure, `fatal: detected dubious ownership in repository at '/github/workspace/./.git'`

We use the template in the cmp-updates repository and we're experiencing the following error:

To the best of my knowledge, nothing was changed in the workflow on our side, and I am not sure where to modify the command as recommended in the error message (--add safe.directory). Is this a global matter, or a problem specific to our repository?

I face similar issues today.

[martinthomson]

Best guess is that something changed in the version of git that is installed. The indicated command already runs with "/github/workspace" as the argument. I've added a workaround, let's try again and see.

I ran the job again - it worked this time. Thank you!
