Ensure that Telephone does not get special core treatment
### Problem/Motivation
Telephone is being moved from core to contrib and it should use `drupal/telephone`

#### Steps to reproduce
### Proposed resolution
Change the composer facade so that the contrib project, Telephone, uses `drupal/telephone` instead of `drupal/telephone-telephone`.
### Remaining tasks
### User interface changes
