Fix Helm Tests

After switching to upstream, the helm test won't run correctly.

The issue is the confluence-application-status-test test which expects an Alpine linux base image in order to run the apk command to install curl. Our prior fix was just to remove the apk command and run with our base image which already has curl.

We'll will need to update gluon to respect the --filter command, or find some other way around this. A Big Big umbrella postRenderer won't work, since confluence is not a part of Big Bug umbrella.

For now, we just removed the chart/templates/tests/confluence-cypress-test.yaml file, so the tests don't run.
