Problem

The v8.0-staging release configuration runs the publish_packages task for the Amazon Linux 2 variants even though Amazon Linux 2 packages are internal-only and are not published. The task fails with a Repobuilder 404, tracked by BF-45848.

Proposed solution

Exclude publish_packages from the release-critical task selectors for the amazon2, enterprise-amazon2, and amazon2-arm64 variants on the v8.0-staging branch.

Acceptance criteria

• The Amazon Linux 2 variants do not generate publish_packages tasks on v8.0-staging.
• Publishing for supported release variants remains unchanged.
• The change is backported through a v8.0 backport ticket.
