Improve the installation process

[lesquoyb]

Is your request related to a problem? Please describe. While the gama installation process is quite simple, it could still be improved by following each platform's philosophy e.g: the user would just have to deal with a package for linux, an installer program for windows and a dmg for macos (which is already the case)

Describe the improvement you'd like

1. Adding github jobs to generate linux packages and windows installers
2. Updating the installation documentation accordingly

Additional context There previously has been some work done to generate a ppa The installation page and a related issue

Here's a list to keep track of each process :

• [x] MacOS
  • [x] DMG signed install archive
• [x] Linux @RoiArthurB
  • [ ] PPA done on #2767 but need to be updated and automated
  • ⛔ Snap for Ubuntu distro
  • .deb is enough
  • ⛔ Flatpak for any distro
  • [ ] (?) AUR for Arch based distro
  • Need to be done from Ubuntu (as Github Actions Runner), so may not be done
• [ ] Windows @lesquoyb
  • [x] MSI installation file
  • [ ] Stable release should be proposed over winget with its installer ✅
  • [ ] winget https://github.com/microsoft/winget-pkgs/pull/4157 (waiting for ZIP install support)

I removed the old repo as it has been re-do inside GAMA in ummisco.gama.product/extraresources/installer/windows 😁

For track : We won't add deb meta-data as we would need to use another utility (AppStream) to package GAMA (cf. https://gitlab.gnome.org/GNOME/gnome-software/-/wikis/software-metadata )
