Audit events for pre-receive secret detection skip via push option

Overview

Related to #457024 (closed)

With #441185 (closed) (MR: !147855 (merged)) we added audit events for:

• When a user skips pre-receive secret detection via a commit message.
• When pre-receive secret detection is enabled/disabled at an instance level.

We also plan to work on:

• Adding push options to allow skipping secret detection in #435315 (closed).

Therefore, we should iterate on audit events created by, adding new events for:

• When pre-receive secret detection is skipped via a push option.

Proposal

In order to account for the changes introduced in #451352 (closed) and #435315 (closed) we should work on the following tasks:

• Create audit event when user skips pre-receive secret detection via push option
• Include branch name in audit log when pre-receive secret detection is skipped via push option or commit message
• Include commit id in audit log when pre-receive secret detection is skipped via push option on a single commit
