Require Node.js >= 20 for Immich CLI; install Node 22 LTS from NodeSource

The Immich CLI uses the File global class which requires Node.js v20+.
The script previously fell back to apt install nodejs which gives v18 on
Ubuntu and fails with "ReferenceError: File is not defined".

Now checks the Node.js major version first. If < 20, offers to install
Node.js 22 LTS from NodeSource before proceeding.
