generate! macros fail when WIT files use syntax defined in the WIT book

[jvatic]

Given a WIT file that contains kebab-case (or otherwise uses the interface syntax defined in the WIT book):

interface hello-world {
  hello-world: func () -> result<string, string>;
}

both host and guest generate! macros fail:

  --> src/app.rs:20:1
   |
20 | / tauri_bindgen_guest_rust::generate!({
21 | |     path: "runner-gui-tauri-commands/hello-world.wit",
22 | | });
   | |__^
   |
   = help: message: called `Result::unwrap()` on an `Err` value:   × unexpected character

Instead I have to change it to not conform to the book at all (so much for syntax highlighting 🙃).

interface hello_world {
  func hello_world() -> result<string, string>
}

I'm assuming this is due to the WIT spec having changed at some point? Are there plans to conform to the most recent WIT spec? (It'd be nice to be able to specify a single WIT file with many funcs and supportive types.)
