The `test_crd_resources` test was failing intermittently in CI with `FileNotFoundError` when validating DataVolume resources in the `openshift-virtualization-os-images` namespace.
The root cause is a timing issue: DataVolumes in this namespace are automatically managed by `DataImportCron` and can be recreated with different image hashes between the time the must-gather is collected (module scope) and when the test executes. For example, a DataVolume might exist as `centos-stream10-1e845a37c663` in the must-gather but be recreated as `centos-stream10-3d2313c9045e` by the time the test runs.

This task should add a filter to skip these volatile DataVolumes during validation, while still testing all other DataVolumes in user namespaces.
