Summary
This PR migrates OCP 4.13 RPM repository downloads from mirror2.openshift.com to the Cloudflare Workers R2 endpoint at openshift-mirror-list.ci-systems.workers.dev to reduce CloudFront egress costs. This follows the successful pilot migration for OCP 4.12 (PR #78292).
Changes

baseurlwas changed fromhttps://mirror2.openshift.com/enterprise/reposync/...tohttps://openshift-mirror-list.ci-systems.workers.dev/enterprise/reposync/..., preserving all path structures and authentication configuration (username_file/password_file settings). CDN-based baseurls (cdn.redhat.com) remain unchanged.Impact
This configuration change affects OCP 4.13 CI builds and release processes, redirecting RPM downloads for multiple architectures (x86_64, ppc64le, aarch64, s390x) and environments (RHEL 8, RHEL 9, ironic, OpenStack) to use the R2 endpoint instead of the CloudFront mirror, reducing infrastructure costs while maintaining availability and package authentication.
