We need to log Audit events related to Group Secrets. We have implemented the basic setup along with auditing of events related to project secrets in [this MR](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/205780). We need to add on top of this to audit events related to group secrets ## Implementation Plan - [Draft MR](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/218603) - Define audit events for CRUD actions on group secrets - Refactor logic in `ee/app/models/secrets_management/audit_log.rb` class to handle both project and group secrets - Update logic in `ee/app/models/secrets_management/audit_log.rb` class to handle group secret actions
