Linters try to determine whether they are running in a git worktree so that `git grep` can be used instead of `grep`. These checks are done in different not truly correct ways and thus the linters don't use `git grep` when running from a worktree subdirectory, e.g. in a git subtree environment. Unify checks using `git rev-parse --is-inside-work-tree`.
