Improve Linux Mint Docker repository detection using UBUNTU_CODENAME

Browse Source 
- Use UBUNTU_CODENAME from /etc/os-release for accurate Ubuntu base detection
- Fallback to version mapping if UBUNTU_CODENAME not available
- Fixes Docker installation on Linux Mint 22.1 where UBUNTU_CODENAME=noble
- More reliable than manual version mapping
