[Defend Workflow] Add Cypress tests to the Kibana release quality gate

[MadameSheema]

Add the @serverlessQA to all the tests you want to have executed in the second quality gate as part the Kibana serverless release.

Please make sure that the tests you are adding are stable in MKI environments (remember that any failure at this stage will block a release to production). The tests should be covering critical paths, behaviours that if are broken or not working properly an SDH or blocker issue might be reported by our customers.

Tests currently enabled in the MKI environment without agent enrollment (agentless) and stable over the past seven days (buildkite builds). All Osquery Cypress tests involve agent enrollment by default and are therefore not included here.
