Fix pre-commit checking provider's doc consistency

The pre-commit was not working since the move of providers to
the `providers` top-level folder (apache#42505) - but we also have
not added many new providers since. This PR updates the check
to work again only for providers that follow the new structure
and to be more verbose on what it is doing.
