Use gtk3 for nativefiledialog

Rational: gtk2 is not maintained anymore and the change was simple.

- Update of nativefiledialog/CMakeLists.txt in order to detect and use
  gtk3
- Updated a few files referencing gtk2, especially:
  - github workflow: I tested that the apt-get update works on ubuntu
    18.03 in a docker container
  - Readme.

This was tested in the following nixpkgs PR: https://github.com/NixOS/nixpkgs/pull/107878
