Disable integration_whl tests on PRs (#2514)

## Why
When this tests were integration tests, they did not do run() part in
-short mode.

After converting them to acceptance I kept them on always in #2471

This PR disables them in short mode (they will still run on main)
because it seems they do expand PR integration test time.
