Generate an audit event if policy limits are exceeded
## Verifications
1. Set up a project with security policies `exceeding` the allowed policy limit:
* [Policy Limit Example](https://gitlab.com/gitlab-org/security-risk-management/security-policies/team-member-environment/imam-test-group/policy-limit/-/blob/main/.gitlab/security-policies/policy.yml?ref_type=heads)
2. Update the Readme in SPP, merge the MR ( wait for `Security::PersistSecurityPoliciesWorker` to execute )
3.Verify an audit event of type `policies_limit_exceeded `is recorded in the Security Policy Project
