Revert "feat: checkout the repository worktree with go-git instead of invoking the git command"

revert for now as the actual git command line is way more robust than go git and this new code immediately failed on the first repository i tested it on, gating it behind an option might make sense though for container applications

This reverts commit e59a558.
