Create user verified trigger

Feature:
Provide a trigger that allows execution of an Action when a user verifies their email by clicking on the Auth0-generated link in the verification email

Description:
The trigger would allow to run custom actions to update external systems etc.

Use-case:
Our systems (email, backend) are out of sync with Auth0 because they don’t know when a user verifies their email. Although this is a crucial step for many apps, this trigger doesn’t exist, so we have to try and keep things in sync by pulling the data from Auth0. It would be much easier to simply trigger an Action (or many depending on the use case).

Hey there @ab-121 thanks for the feedback, always appreciated!
