Notify Org admins when a managed user joins a product outside their Organization

Summary

Atlassian presented the feature Discovered products which gives the ability for Org admins to see if their managed users created products outside their Organization.

Currently the feature also sends notifications for Org admins when a managed user creates a product outside their Org, but not when they join a different product.

Suggestion

Add the ability to receive notifications when a managed user joins a product/site outside of the Org.
