chore: use self hosted runners

[waskow-consensys]

This repo has been identified as a higher cost repo in our Org.

Move runners to self hosted runners to mitigate cost and increase performance.

Thanks!

Note

Move PR and push workflows to a self-hosted Ubuntu runner, update OS condition checks, and add 30m timeouts to tagged tests.

• CI (GitHub Actions)
  • PR workflow (.github/workflows/pr.yml):
    • Switch test job runner to gha-runner-scale-set-ubuntu-24-amd64-xxl.
    • Add -timeout=30m to tagged go test commands.
  • Push workflow (.github/workflows/push.yml):
    • Replace matrix OS ubuntu-latest-128 with gha-runner-scale-set-ubuntu-24-amd64-xxl.
    • Update Ubuntu checks to startsWith(matrix.os, 'gha-runner-scale-set-ubuntu').
    • Gate solc deps install and Ubuntu-specific tests behind the new runner check.

Note

Switch test jobs to a self-hosted Ubuntu runner label across PR and push workflows.

• CI (GitHub Actions):

  • Update test job runners to self-hosted gha-runner-scale-set-ubuntu-22.04-amd64-xxl.

    • /.github/workflows/pr.yml: runs-on changed for test job.
    • /.github/workflows/push.yml: matrix os replaces ubuntu-latest-128 with gha-runner-scale-set-ubuntu-22.04-amd64-xxl.

Sure, I think we wouldn't have a issue changing runners. However what are the specs of the machine? Some tests are starting to timeout which didn't before: https://github.com/Consensys/gnark/actions/runs/18847896561/job/53845181796#step:7:47

We'll discuss maybe it is worth it to segregate the tests to have a fast path for PRs and then longer-running tests for end-to-end integration.

Looks good! Lets try it out on master as well.
