E0308 type mismatch for arrays doens't offer to fix the length (unlike E0658)

[lnicola]

Code

const NUMBERS: [u8; 3] = [10, 20];

Current output

  |
7 | const NUMBERS: [u8; 3] = [10, 20];
  |                          ^^^^^^^^ expected an array with a fixed size of 3 elements, found one with 2 elements

Desired output

  |
7 | const NUMBERS: [u8; 3] = [10, 20];
  |                     ^ help: consider specifying the array length: `2`

Rationale and extra context

Works nicer in an IDE.
