* bug#61303: 29.0.60; rust-ts-mode does not consistently fontify nested macro-invocations

Hey there.

Thanks for another tree-sitter based mode to hack at :D

I think I've found an error/lacking in rust-ts-mode where we may have to 
move upstream to fix it.

Consider the following contrived (and yes, not very idiomatic) rust-code:

let result = format!("{}{}",
     "Well yes",
     format!("Or {} no?", "possibly"));

With rust-ts-mode first format! invocation will get highlighted as a 
macro-invocation, while the second will not.

Inspecting this using treesit-explore-mode, I get the following tree:

(let_declaration let pattern: (identifier) =
   value:
    (macro_invocation macro: (identifier) !
     (token_tree (
      (string_literal " ")
      (string_literal " ")
      (identifier)
      (token_tree (
       (string_literal " ")
       (string_literal " ")
       ))
      )))
   ;)

Notice the lack of a second/nested "macro_invocation"-node. Instead the 
second macro is just denoted as a "identifier".

To fix this, we'll probably need to upstream some bug-reports and PRs?

Sounds like it!  Just in case - the code compiles, right?

Yes. This is compilable, runnable rust-code.
