Description
Issue
When using an Alpine image in Github Actions runner, actions/checkout will put git into a bad state, causing go build to run into a vcs issue. go build is running into issue because its detecting git info through the .git folder but is not able to get the version info it needed and will exit with code 1.

note: I know there are work around like passing the flag -buildvcs=false to go build but I was curious what cause this issue
