💡 Summary

What is the work, as a high-level summary?
Rego checks were updated to test MS.AAD.3.3v1 with authenticator found in issue #1484, as a result the policy has been decoupled from MS.AAD.3.1v1 and needs to update the policy and description.

Motivation and context

Why does this work belong in this project?

This would be useful because the baseline policy needs to be aligned with the implementation of the new rego checks.

Implementation notes

New policy name:

New policy description:
Rationale: This policy helps protect the tenant when Microsoft Authenticator is used by showing user context information, which helps reduce MFA phishing compromises.
