If a workspace was opened as `/path/to/workspace` instead of `/path/to/workspace/` (notice the trailing slash), the check for `url.deletingLastPathComponent() == self.projectRoot` failed because deleting the last path component always produces a URL with a trailing slash and URL considers two path different if they mismatch in their trailing slash usage.
Use `DocumentURI` for equality checking, which is a little more lenient with declaring equality, including with regard to trailing slashes, and whose equality definition aligns better with what we want in SourceKit-LSP.
I searched for other usages of `==` between URLs and there doesn’t seem to be any similar issues.
