Remove unused Result wrapper for Path->Url conversion

Internally the LSP client should hold workspace folders as paths. Using
URLs for this type is inconvenient (since we compare it to paths) and
might cause mismatches because of URLs not being normalized. The URLs
must be paths anyways so we can convert these types lazily when we need
to send them to a server.

This fork focuses on usability improvements that make the types easier to work with for the Helix codebase.
+
+The URL type has been replaced with a newtype wrapper of a `String`. The `lsp-types` crate at the forked version used [`url::Url`](https://docs.rs/url/2.5.0/url/struct.Url.html) which provides conveniences for using URLs according to [the WHATWG URL spec](https://url.spec.whatwg.org). Helix supports a subset of valid URLs, namely the `file://` scheme, so a wrapper around a normal `String` is sufficient. Plus the LSP spec requires URLs to be in [RFC3986](https://tools.ietf.org/html/rfc3986) format instead.
