packaging: script: Use rockylinux prefix on package testing script

[cosmo0920]

For safety, we should use rockylinux/ prefix for testing package installations on rockylinux.
Rockylinux 8 and 9 are already existing in library prefix which is the default prefix of Docker pulling destination but rockylinux 10 is not there.
Plus, for simplicity of maintenance, just align the usage of container names with package building containers of rockylinux.

packaging/test-release-packages.sh (1)

54-56: The change to use rockylinux/rockylinux namespace for all Rocky Linux versions is correct and necessary.

The official Docker Hub documentation only lists versions 8 and 9 for the library prefix, meaning Rocky Linux 10 is only available as rockylinux/rockylinux:10. The rockylinux/rockylinux namespace is the official Rocky Linux image, and this change maintains consistency across all supported versions while enabling Rocky Linux 10 support.

The updated image references are accessible and valid for use.
