fix: For GPU based E2E test to use Qwen2.5 example

[jaiakash]

What you would like to be added?

In #2762 we added feature to run GPU based E2E test on OCI VM. The issue was that it used HF_TOKEN for downloading the model. Giving the PRs to access that token was raising CVEs, even using environments was a scalable method.

This issue tracks to use the Qwen2 model for GPU E2E test which doesnt require any token to be used.
