Switch GNOME 3 theme to Dark Mode and back.

This extension is still a BETA version. It only supports Adwaita and Adwaita-dark for now. I'm working on a new version where you can choose what theme you prefer for a dark and non-dark mode.

• Fedora 30 - GNOME 3.32.2

• Access GNOME Shell Extension site.
• If you have GNOME Shell integration set, you only have to switch the toggle on.
• If you do not have GNOME Shell integration, you must have to follow a few more steps: Look this tutorial
