"git worktree remove" basically consists of two things
- delete $GIT_WORK_TREE
- delete $GIT_DIR (which is $SUPER_GIT_DIR/worktrees/something)
If $GIT_WORK_TREE is already gone for some reason, we should be able
to finish the job by deleting $GIT_DIR.
Two notes:
- $GIT_WORK_TREE _can_ be missing if the worktree is locked. In that
case we must not delete $GIT_DIR because the real $GIT_WORK_TREE may
be in a usb stick somewhere. This is already handled because we
check for lock first.
- validate_worktree() is still called because it may do more checks in
future (and it already does something else, like checking main
worktree, but that's irrelevant in this case)
