Fix confirmations and notifications validation to accept objects

The Gravity Forms REST API v2 returns confirmations and notifications as
objects keyed by ID, not arrays. The validation was incorrectly using
validateArray()/`.array()` which rejected the correct format. Changed
both validators to use validateObject()/`.object()` and added missing
notifications validation.
