feat(rocky): support Rocky Linux Modular Package

[MaineK00n]

Background

Rocky Linux's errata is not able to accurately detect the modular package.
Therefore, it is necessary to either wait for Rocky Linux to fix the errata or to extend the errata.

How to extend errata

Look for the affected package in the updateinfo.xml in the modules.yaml and find the matching module.
It is successful only if it can be completely broken down into modules according to modules.yaml.
