chore(EC-2153): remove RH-specific policy digest defaults

[jsmid1]

DO NOT MERGE BEFORE conforma/infra-deployments-ci#236.

Remove the RH Konflux-specific POLICY_BUNDLE_DIGEST default from the generic task definitions. Generic consumers now receive an empty default; the Konflux release workflow injects the released digest into its generated task output.

Related: conforma/infra-deployments-ci#236.

Testing: make lint

Resolves: EC-2153

Walkthrough

Both Tekton tasks now set an empty default for POLICY_BUNDLE_DIGEST, and their documentation no longer lists a default. The script that updated pinned digests across task definitions and related files was removed.

Risk Assessment: moderate (2/5)

Details

Low-risk refactor by a frequent contributor moving the POLICY_BUNDLE_DIGEST default from tasks to the pipeline, with the main concern being silent behavioral change for direct task users who bypass the pipeline.

Forward POLICY_BUNDLE_DIGEST from the enterprise-contract pipeline.

The enterprise-contract pipeline does not define or forward POLICY_BUNDLE_DIGEST. Its reachable verify-enterprise-contract task therefore uses the new empty default. The pinning script skips the policy-bundle override when the value is empty, so Konflux runs no longer use the former pinned digest.

Add the digest default and forward it to the task while keeping the task default empty.
