Fix version worktree (#16431)

* git worktree friendly precomit install

* worktrees don't have a .git directory. Before, docker-compose would
  trigger pre-commit install and fail.

* make docker-compose work in git worktree

* AWX tries to discover the version via info stored in .git/ dir.
  setuptools-scm is capable of finding the .git/ dir, starting from a
  worktree, but is unable because only the worktree is mapped into the
  container, not the .git/ dir itself. Thus, we have to detect and pass
  the version into the container from outside. That is why this change
  landed in the Makefile.
