Fix: OpenShift E2E Workflow Not Running

[ev-shindin]

Summary

Fixes the CI - OpenShift E2E Tests workflow which was completely broken due to duplicate environment variable definitions causing GitHub Actions to reject the workflow file.

Problem

The OpenShift E2E workflow (.github/workflows/ci-e2e-openshift.yaml) was not running on any PRs. GitHub Actions was rejecting the workflow file with the error:

Invalid workflow file: .github/workflows/ci-e2e-openshift.yaml#L1
(Line: 479, Col: 11): 'BENCHMARK_MODE' is already defined
(Line: 536, Col: 11): 'BENCHMARK_MODE' is already defined

This prevented the entire workflow from executing, which is why:

• No OpenShift E2E checks appeared in PR status
• /ok-to-test comments had no effect
• The workflow appeared to be completely inactive

Root Cause

Two env blocks in the workflow had duplicate BENCHMARK_MODE definitions:

1. "Deploy WVA and llm-d infrastructure" step (lines 462-491):

   • Line 468: BENCHMARK_MODE: "false" (original)
   • Line 479: BENCHMARK_MODE: "false" (duplicate)

2. "Deploy Model B infrastructure" step (lines 515-548):

   • Line 521: BENCHMARK_MODE: "false" (original)
   • Line 536: BENCHMARK_MODE: "false" (duplicate)

YAML does not allow duplicate keys in the same mapping, and GitHub Actions enforces this validation.

Fix

Removed the duplicate BENCHMARK_MODE definitions at lines 479 and 536, keeping the original definitions at lines 468 and 521.

Let's merge this one first as it only fixes the CI workflow file. @WheelyMcBones can you then rebase you PR?
