Similarly named macros aren't suggested for incorrect macro names in anyhow

Code

use anyhow;

fn main() {
    // should be format_err!()
    anyhow::format_error!("foo");
}

Current output

error[E0433]: failed to resolve: could not find `format_error` in `anyhow`
 --> src/main.rs:5:13
  |
5 |     anyhow::format_error!("foo");
  |             ^^^^^^^^^^^^ could not find `format_error` in `anyhow`

Desired output

error[E0433]: failed to resolve: could not find `format_error` in `anyhow`
 --> src/main.rs:5:13
  |
5 |     anyhow::format_error!("foo");
  |             ^^^^^^^^^^^^ help: a macro with a similar name exists: `format_err`

Rationale and extra context

This works for ppanic!(), so maybe the threshold similarity threshold isn't being met in the anyhow case?

Other cases

No response

Anything else?

No response

Reproduce the Rust compiler diagnostic with the anyhow::format_error! example and compare it with the ppanic! case mentioned in the issue. Start by tracing the compiler's unresolved macro-name suggestion logic and its similarity threshold; done means the error suggests format_err! for the shown code without regressing existing suggestions.
