Integrate TTK or equivalent into Bicep pull request builds

We should block examples violating security rules from being checked into the repo. This could mean integrating the TTK or any new upcoming equivalent tools.

Start by identifying the pull request build configuration and how example security rules are currently checked. Compare TTK with possible equivalent tools and define a build failure for violating examples; the issue names no specific file or test, so the integration point and validation steps must first be established.
