Enhance package installation process in cyberpanel.sh for RHEL 9+ systems

- Added steps to clean and make cache before and after EPEL and MariaDB repository installations to prevent conflicts.
- Implemented repository priority settings to avoid package conflicts during installation.
- Included checks for repository and package conflicts, with fallback installation strategies for MariaDB.
- Organized package installation into logical steps to ensure proper dependency resolution and system stability.
- Finalized with a cache clean and system update to maintain consistency.
