Migrate from deprecated oc-installer to openshift-tools-installer

[snecklifter]

Summary

• Replace redhat-actions/oc-installer@v1 with redhat-actions/openshift-tools-installer@v2 in the multicluster e2e workflow

Why

redhat-actions/oc-installer is deprecated:

• The download mirror it points to has not been updated since December 2020
• The action now emits a deprecation warning at runtime (redhat-actions/oc-installer#32)

openshift-tools-installer is the actively maintained successor, supporting semver ranges, arm64, cross-workflow caching, and 18+ tools.

Test plan

• Verify the multicluster e2e workflow installs oc successfully with the new action

Hi @snecklifter. Thanks for your PR.

I'm waiting for a stackrox member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
