Enhance MariaDB repository configuration and AlmaLinux 9 support

- Updated MariaDB repository URLs in cyberpanel_upgrade.sh and cyberpanel.sh to use the mirror site for improved reliability.
- Added logic in cyberpanel_upgrade.sh to determine the appropriate MariaDB repository based on the OS version.
- Introduced a new method in install.py to apply specific fixes for AlmaLinux 9, including the installation of compatibility packages.
- Removed the obsolete simple_install.py script to streamline the installation process.
