Mark /app as safe directory for Git

[danut007ro]

In my github actions I got error

The repository at "/app" does not have the correct ownership and git refuses to use it:

fatal: detected dubious ownership in repository at '/app'
To add an exception for this directory, call:

	git config --global --add safe.directory /app

This PR fixes the issue by adding an actions to mark /app directory as safe for git.

Hi @danut007ro!

I would suggest adding this command to the Dockerfile for the frankenphp_dev target. WDYT?

[danut007ro]

Sure @7-zete-7 , have a look now. Thanks

Hum... I don’t think we should add this.
Git isn’t meant to be used inside the container, and this just bypasses the “dubious ownership” warning instead of addressing a real need.
It also adds an unnecessary global config inside the image.

Closing, as I am unable to reproduce on a new project. Will reopen if needed. Thank you.

Managed to reproduce on a new clean project. Here's the PR on that new project https://github.com/danut007ro/symfony-docker-test/pull/1/files with result https://github.com/danut007ro/symfony-docker-test/actions/runs/16966099280/job/48090334555?pr=1

As you can see, the warning occurs when running composer audit command. Maybe there is another way to fix it?
