Add KDE Neon to authorised distro for install script

[eapetitfils]

KDE Neon is based off Ubuntu. I just installed it by changing the script manually and I can connect as usual.

The content of os-release is as follows:

$ cat /etc/os-release
PRETTY_NAME="KDE neon 6.1"
NAME="KDE neon"
VERSION_ID="22.04"
VERSION="6.0"
VERSION_CODENAME=jammy
