Use cloudfront_staging_url for Windows pytorch testing workflow.

Motivation

Follow-up to #1110 and #1382. Progress on #1072.

This test run https://github.com/ROCm/TheRock/actions/runs/17662170140/job/50199734639#step:6:37 failed with

Technical Details

The build job only uploaded to v2-staging, so the test job should download from v2-staging, not v2.

The change here was made on Linux but was overlooked during the porting to Windows:

The https://github.com/ROCm/TheRock/actions/runs/17585233778 test run mentioned at #1382 (comment) did not run any tests and did not exercise this code because we only have gfx1151 runners and that used gfx110X-dgpu.

Those are easy mistakes to make. We could

1. Rename the cloudfront_url input to carry more meaning about what it represents, like package_index_url or staging_package_index_url
2. Bring up runners for more GPUs or change the default workflow_dispatch GPU type to one we have test runners for

Test Plan

Untested.

Test Result

Nope.

Agree with both suggestions. Especially the renaming is a low hanging fruit.

The change looks good.

I ran the workflow with the changes on both the Archs gfx1151(We have runners for this) and gfx110(We dont have runners). Unfortunately missed the test step on my run for for gfx1151 below, as builds were failing for gfx1151 and did not proceed to the test step.

Run on gfx1151:

LGTM!
