[Launcher] Add option for experimental (master) build

[SpaceMonkeyy86]

There could be an option in the settings for switching to the master branch for the latest changes. This would allow the community to test out the new updates, find any bugs that pop up, and give feedback on the changes. However, this version would not be supported officially by the staff and there would have to be a warning that additional glitches may occur.

This is currently not possible as we can't implement CI/CD. We maybe can do that with full linux support.
