user_id and is_group_number deprecated on phone numbers

The user_id and is_group_number fields on the Phone Number API are deprecated, both as query filters when listing phone numbers and as fields in phone number responses. They will be removed in a future update.

The distinction between group and personal phone numbers is being retired. To filter phone numbers by user, use the new participant_user_id query parameter, which returns every number the user participates in. Because it also matches group numbers the user belongs to, it can return more results than user_id did.

The user_id and is_group_number fields are still returned in responses, and reading them requires no changes today. Both fields will be removed in a future update.
