[Defend Workflows] Skip Cypress tests on MKI executions (#186120)

## Summary

The
`x-pack/plugins/security_solution/public/management/cypress/e2e/response_actions/response_console/scan.cy.ts`
test is failing on MKI environments (the periodic pipeline).

This is because the test in order to work need to have a feature flag
enabled. FF are not currently supported on MKI environments, that is why
in this PR we are skipping it from MKI environments by adding
`@skipInServerlessMKI` label to it.
