Incorrect suggestion to add turbofish when `>` is missing

[RalfJung]

Code

type One = for<'b, 'a> fn(Box<dyn Send + 'a + 'b);

Current output

error: generic args in patterns require the turbofish syntax
 --> src/lib.rs:1:30
  |
1 | type One = for<'b, 'a> fn(Box<dyn Send + 'a + 'b);
  |                              ^
  |
help: use `::<...>` instead of `<...>` to specify lifetime, type, or const arguments
  |
1 | type One = for<'b, 'a> fn(Box::<dyn Send + 'a + 'b);
  |                              ++

Desired output

No response

Rationale and extra context

Adding the turbofish is wrong, so the output should be something else that doesn't ask me to add the turbofish.

Other cases

No response

Rust Version

1.76.0 (via Playground), unchanged on current nightly

Anything else?

No response

If there is an extra >, the compiler is also suggesting add turbofish:

type One = for<'b, 'a> fn(Box<dyn Send + 'a + 'b>>);

output:

 --> ./t/test.rs:1:30
  |
1 | type One = for<'b, 'a> fn(Box<dyn Send + 'a + 'b>>);
  |                              ^
  |
help: use `::<...>` instead of `<...>` to specify lifetime, type, or const arguments
  |
1 | type One = for<'b, 'a> fn(Box::<dyn Send + 'a + 'b>>);
  |                              ++

I am currently working on a PR for these two issues. I already fixed the original part of this issue with no tests failing
