Add Ubuntu support to HyperHDR Github Pages APT repository

[awawa-dev]

Add native support for Ubuntu in HyperHDR APT repository.
Installers for the latest Ubuntu LTS and latest non-LTS version (if newer than LTS) will be available for the APT repository.
Currently it means: Ubuntu 22.04 LTS (jammy) and 23.04 (lunar)

Github Action test versions have support only for latest LTS.

The Ubuntu repository is already uploaded and ready to use

How to configure the HyperHDR repository with a single command is explained here:
https://awawa-dev.github.io/

You don't need to use Debian repository anymore for this system. If you have Debian repo already installed in your Ubuntu (using the old manual) then you can switch it to Ubuntu repo using following commands:

sudo rm /etc/apt/sources.list.d/hyperhdr.list

echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/hyperhdr.public.apt.gpg.key] https://awawa-dev.github.io $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/hyperhdr.list > /dev/null

sudo apt update

// this will reinstall HyperHDR using native Ubuntu installer
sudo apt install hyperhdr -y --reinstall
