Change tests for MS.AAD.5.4v1 for teams group consent to not-implemented as setting is deprecated

[rmoffitt-m]

🗣 Description

Update rego for MS.AAD.5.4v1 to not-implemented as the group consent setting is discontinued.
In case the setting is not discontinued in other Azure implementations (e.g. GCC), the rule will continue to function as expected.

💭 Motivation and context

Changes the tests to not-implemented to avoid falsely failing a test that can no longer be performed. The baseline can be removed in a future release.
Closes #1139

🧪 Testing

Run AAD tests and verify that the test result for MS.AAD.5.4v1 is N/A instead of failed and criticality is not-implemented. Ensure tests can still successfully run.

Reviewed the updated Rego code and it is consistent with other deprecated setting changes. The HTML report shows 5.4 as N/A and deprecated as does the JSON showing as Shall/Not-Implemented.
Unit tests pass.
Functional test for AAD 5.4 does not pass. Currently it fails with an error indicating an issue running the test. Also found issues with the configuration of the functional test itself. See comments and recommended changes below to resolve.

Latest commit addresses the failed functional test issues previously noted. Looks good.

new results consistent with other not implemented policies. Create a new issue for the removal of the setting from the SCB set for the "m" release milestone with a reference to this PR and issue!

Nice work Rich. Seems to match up with other deprecations we have incorporated before.
