tide: set github_merge_blocks_policy to block for all RHDH repos

[zdrapela]

Summary

• Sets github_merge_blocks_policy: block for all RHDH repositories that have Tide config in openshift/release
• Same Tide feature as tide: enable github_merge_blocks_policy for repos with recent merge failures #80150 / tide: set github_merge_blocks_policy to block for OADP repos #82902 — makes Tide respect GitHub mergeStateStatus and skip PRs blocked by branch protection instead of retry-looping
