tmlanguage contribution is inaccurate

[CoenraadS]

Hello

The tmlanguage this extension contributes is less accurate then the one that ships with VSCode.

VSCode:

Rust Extension:

As you can see, now VSCode thinks <> are matching pairs

if a <= b {
  println!("blabla");
}

if a >= b {
  println!("blabla");
}

The Rust grammar is the one that's shipped by the VSCode (which itself seems to be the one based on the Atom one?). Hopefully the VSCode might consider either including the syntax highlighting in the protocol or change the underlying tooling; otherwise we'd need to provide our own grammar as part of this extension.
