Ramon Roche d9996742be setup: drop Ubuntu 18.04/20.04 support from ubuntu.sh
Remove Gazebo Classic installation branches for Ubuntu 18.04 and 20.04.
The script now only supports Ubuntu 22.04 and 24.04 with Gazebo Harmonic.

Supported Ubuntu LTS versions going forward:
- Ubuntu 24.04 (primary, used in CI and release builds)
- Ubuntu 22.04 (secondary, still supported)

When Ubuntu 26.04 LTS releases we will bump to 26.04/24.04.
