Pin Dataproc 2.2 Ubuntu presubmit image

[nvliyuan]

Summary

• Pins the Dataproc 2.2 Ubuntu presubmit job to 2.2.81-ubuntu22 to avoid the current 2.2.82-ubuntu22 DKMS failure with nvidia-driver-550-open on 6.8.0-1058-gcp.
• Updates the test helper to treat patch-level 2.2 images such as 2.2.81-ubuntu22 as 2.2 images for the existing public IP behavior.

Test plan

• IDE lint check for edited files
• Running bazel test --jobs=1 --local_test_jobs=1 --flaky_test_attempts=1 --action_env=INTERNAL_IP_SSH=true --test_output=errors --test_arg=--image_version=2.2.81-ubuntu22 rapids:test_rapids on yuanli@spark-yuanli:~/work/csps/dataproc/ci-fix-validation/initialization-actions

Code Review

This pull request pins the Dataproc 2.2 Ubuntu image version to 2.2.81-ubuntu22 in the Cloud Build configuration to bypass a DKMS issue with nvidia-driver-550-open on the 6.8.0-1058-gcp kernel. To support this specific version pinning in integration tests, the exact list match for IMAGE_VERSION_2_2 is replaced with a regular expression pattern (IMAGE_VERSION_2_2_PATTERN) that matches both minor and patch versions of Dataproc 2.2 images. There are no review comments, and I have no feedback to provide.

Closing this workaround PR. The fix should be made in spark-rapids.sh instead of pinning the presubmit image.
