  Below is an example diff for F401:

  -unused.py:8:19: F401 [*] `pathlib` imported but unused
  +F401 [*] `pathlib` imported but unused
  +  --> unused.py:8:19
      |
    7 | # Unused, _not_ marked as required (due to the alias).
    8 | import pathlib as non_alias
  -   |                   ^^^^^^^^^ F401
  +   |                   ^^^^^^^^^
    9 |
   10 | # Unused, marked as required.
      |
  -   = help: Remove unused import: `pathlib`
  +help: Remove unused import: `pathlib`

  For now, the primary difference is the movement of the filename, line number, and column information to a second line in the header. This new representation will allow us to make further additions to Ruff's diagnostics, such as adding sub-diagnostics and multiple annotations to the same snippet.
