Github pipelines using git with fix for CVE-2022-24765 broken due to insecure directory.

[demerphq]

Description
Our CI jobs were failing with the following error:

        Run git remote set-url origin "***[github.com/$GITHUB_REPOSITORY](http://github.com/$GITHUB_REPOSITORY)"
        fatal: unsafe repository ('/__w/perl5/perl5' is owned by someone else)
        To add an exception for this directory, call:
    
        git config --global --add safe.directory /__w/perl5/perl5
        Process completed with exit code 128.

As far as I understand it this is due to the fix for CVE-2022-24765.

I have already pushed a fix. This is retrospective issue for the records.

Steps to Reproduce
Use a modern git on a directory that is shared.

Reproducing this on github might be hard, I have already pushed a fix in: #19618

Specifically: 4303fd2

Expected behavior
CI not to die due to insecure directories.

Perl configuration
N/A.
