Revisit CI Cypress tests for Twistlock

For some context on what appears to be the issue with cypress and twistlock, see this thread: !105 (comment 1593582)

In the previous tag upgrading to v30 twistlock's basic cypress test was disabled as there were issues with it actually executing, running successfully and providing useful information.

Improve twistlock's cypress tests at https://repo1.dso.mil/big-bang/product/packages/twistlock/-/blob/main/chart/tests/cypress/e2e/twistlock-health.spec.cy.ts to include logging in with the configured admin user from the init portion of the values file and associated script and checking other functionalities of PCC/Twistlock.
