Description of problem:

In my PR for updating dependencies, I noticed that golint was failing with a deprecated function in the integration tests:

https://gcsweb-ci.apps.ci.l2s4.p1.openshiftapps.com/gcs/test-platform-results/pr-logs/pull/openshift_installer/10060/pull-ci-openshift-installer-main-golint/1985679181924536320/artifacts/test/build-log.txt

The note says:

    testscript.RunMain is deprecated: use [Main], as the only reason for returning exit codes
was to collect full code coverage, which Go does automatically now:
https://go.dev/blog/integration-test-coveragedeprecateddefault

I gave a quick shot at fixing it and also asked Claude, but it was not obvious how to use Main instead of RunMain. So instead I'm putting a nolint on the PR and we can fix later.

Version-Release number of selected component (if applicable):

    main

How reproducible:

Steps to Reproduce:

 go-lint with https://github.com/openshift/installer/pull/10060 or on main once that marges
    

Actual results:

Expected results:

    Remove the //nolint and go-fmt should pass
