fmt: check gosimports during pre-commit hooks (#29520)

`gosimports` is the preferred style for module imports and it is
enforced via CI. I've found that things often manage to drift so I've
taken the liberty to update our pre-commit hook to verify our imports
formatting before a change is committed.

Along with updating the formatting helper I've also run `make fmt` to
resolve any formatting drift that managed to make it into the codebase.
