Add more packages and try to keep package versions up to date

The number of software packages in openEuler is limited, with some packages like Remmina missing entirely. The software package versions are outdated—for example, in openEuler 24.03, cgroup is still at version v1, requiring kernel parameter modifications when installing Kubernetes. We hope to increase the number of software packages in openEuler and ensure they are kept up to date. Additionally, we urge the prompt adoption of dnf5 to replace dnf4.

openEuler有没有类似于RHEL的EPEL的镜像源可以使用？目前openEuler 24.03 LTS的镜像源里面缺失很多常用软件，比如btop，需要源码编译安装
