Make `deduplicate_dirs` generic

This commit updates the signature of `deduplicate_dirs` to allow passing any type compatible with `Path` instead of requiring `&str`.

This change aligns the API with Rust's standard library, which uses `AsRef<Path>` for its FS functions.

This is an extra feature and should not break any existing code since `&str` implements `AsRef<Path>`.
