Describe issue

My workflow uses the custom action rlespinasse/github-slug-action@v5.

When running the step, this happens:

[Build and Push Docker Image/build] [DEBUG] Writing entry to tarball workflow/2-composite-prefligth.sh len:34
[Build and Push Docker Image/build] [DEBUG] Extracting content to '/var/run/act'

[Build and Push Docker Image/build]   ❌  Failure - Main $GITHUB_ACTION_PATH/preflight.sh
[Build and Push Docker Image/build] exitcode '126': failure

During troubleshooting, I recognized that, immediately after cloneing the action's repository, git diff from inside ~/.cache/act/rlespinasse-github-slug-action@v5 shows the following:

~/.cache/act/rlespinasse-github-slug-action@v5 $ git diff
diff --git a/preflight.sh b/preflight.sh
old mode 100755
new mode 100644

When following the trail, I found that this go-git issue describes what's going on, so it really seems to be an upstream issue.

The workflow below is the MRE, thus doesn't do anything useful.
