Added operations for Diahook webhooks

This release adds three operations in the SDK:

• CreateDiahook: Creates a new Diahook app for the given instance
• RefreshDiahookURL: Returns a newly generated url for access to Diahook's management UI for the specific app
• DeleteDiahook: Deletes the Diahook app associated with the given instance

Simplify client cookie verification process

The backend API now returns all the client's sessions along with the client when verifying a client cookie.
This simplified the verification process on the SDK side, since there is no need for two API calls when verifying the client cookie.

Custom attributes on users

Users can now have custom attributes. These can be either private (using the private_metadata field) or public (via the public_metadata field).

Simplified verification logic, handle Clerk error responses

The verification logic is now simplified. It relies solely on the existence of the _clerk_session_id to determine whether it will use a particular session or the last active one.

Also, the SDK can now handle the new Clerk's error response structure.
