chore: remove stray root services/provider.php

The canonical webservices provider lives in
source/packages/plg_webservices_mokosuitebackup/services/provider.php.
This root-level copy is an orphaned duplicate — nothing references it and
it is not part of any packaged extension. Recovered from a stash of
previously-set-aside cleanup.
