"Dubious ownership" Git error on some environments

[AlexTMjugador]

I'm using this action in a workflow job that runs on a Debian Bullseye Docker container on a GitHub-hosted Ubuntu runner (more precisely, it is configured as runs-on: ubuntu-latest and container: debian:bullseye-slim).

Hours ago, the Docker image and/or Debian repositories changed so that apt-get install git began to install a Git version with a different Debian security patch:

New version Old version

I suspect that this new security patch does not play nice with this action and Docker containers, as this error now shows up when running the action, and I wasn't able to identify other relevant environment changes between the latest successful run and the first failed run:

While I'm not sure whether this action is to blame or not, and I've already implemented a workaround for this problem in my workflow, the fact that it started happening overnight and other actions work fine suggests that it's likely this action could handle these relatively new Git security features better.
