chore: mark workspace apps and workspace agents as unaudited (#18761)

The main goal of this PR is to remove Workspace Apps and Workspace Agents from the auto-generated audit log documentation, that incorrectly claims they are audited resources (no longer true with the addition of the connection log).

Though I believe we haven't touched any codepaths for returning audit logs, this PR also adds a test that ensures we continue to return *existing* connection, disconnect and open events correctly from the audit log API.
