Build/Test Tools: Fix workflow names in test old branches workflow.

After the changes in [58165] and [58645] and all associated backports, the workflow that dispatches regular testing in older branches needed to be updated.
- The `test-npm.yml` workflow no longer exists.
- The `test-build-processes.yml` has taken the place of `test-npm.yml` in all branches.

Also, the workflow will now run whenever an old version of the reusable PHPUnit workflow is updated (v1 or v2). This is to ensure the changes don’t cause any compatibility problems in older branches.

See #61213.
