Allow numbers in module_name_repetitions

[TomFryersMidsummer]

Summary

Suppose I have a module vector, containing a Vector2 type. This seems fine to me – I can't name the type 2, after all. However module_name_repetitions disagrees.

Maybe this should apply to all short affixes more generally (one or perhaps two letters). I'm not sure.

Lint Name

module_name_repetitions

Reproducer

I tried this code:

pub mod vector {
    pub struct Vector2(pub f64, pub f64);
}

I saw this happen:

$ clippy-driver --crate-type lib -Wclippy::pedantic test.rs 
warning: item name starts with its containing module's name
 --> test.rs:2:16
  |
2 |     pub struct Vector2(pub f64, pub f64);
  |                ^^^^^^^

  = note: `-W clippy::module-name-repetitions` implied by `-W clippy::pedantic`
  = help: to override `-W clippy::pedantic` add `#[allow(clippy::module_name_repetitions)]`

I expected to see this happen: [no error]
