Description

Resolve the Node runtime deprecation warnings in the YARN resource cost checks by using NVIDIA/spark-rapids-common/checkout@main and actions/setup-python@v7. Keep the Python 3.10/3.11/3.12 matrix, triggers, and test commands unchanged.

Validation

• All 60 YARN resource cost unit tests passed in an isolated environment with the declared zstandard dependency installed.
• YAML parsing and structural comparison passed: only the action references change.
• git diff --check passed.
• The complete hosted Python-version matrix remains to be validated in CI.

Deprecation References

• GitHub Actions Node 20 deprecation announcement: recommends updating to actions that run on Node 24; Node 20 removal is scheduled for September 23, 2026.

Summary

This PR updates the YARN resource-cost workflow's checkout and Python setup actions while retaining its triggers, Python matrix, and test commands.

• Replaces actions/checkout@v4 with the shared NVIDIA checkout action.
• Upgrades actions/setup-python from v5 to v7.
• Leaves one non-blocking supply-chain hardening concern because the checkout action follows a mutable branch.
