Add suggestion to remove visibility qualifier in `error[E0449]: visibility qualifiers are not permitted here` for `cargo fix`

[ElectrifyPro]

Code

trait Fun {
    pub fn test() {}
}

Current output

error[E0449]: visibility qualifiers are not permitted here
 --> src/main.rs:2:5
  |
2 |     pub fn test() {}
  |     ^^^
  |
  = note: trait items always share the visibility of their trait

Desired output

error[E0449]: visibility qualifiers are not permitted here
 --> src/main.rs:2:5
  |
2 |     pub fn test() {}
  |     ^^^
  |
  = note: trait items always share the visibility of their trait
help: remove the qualifier
  |
2 |     fn test() {}
  |

Rationale and extra context

This error has a very trivial no-nonsense solution, and it would be nice for the compiler to provide a suggestion so that it can can easily be fixed with cargo fix.
