refactor(linter/import): better diagnostic messages for import/no-duplicates (#6693)

## What This PR Does
- Include the offending module in the diagnostic's message
- Add a help message
- Add label text to the first module request

It also includes these minor refactors:
- Move `check_request` closure into a separate function
- Move diagnostics creation to a separate function (same as every other rule)
