Three configuration files are updated to support OpenShift 4.21.13 release images across multiple architectures. Version and URL entries for 4.21 (x86_64, arm64, multi) are updated from 4.21.12 to 4.21.13, with the x86_64 entry gaining a default: true flag. ConfigMaps and templates are expanded with additional release metadata.
