Mark draft releases in SlimeVR Server or in Flasher not to show up in default

[unlogisch04]

I think we should add a exclusion for draft releases or only show them if development mode is on, and also mark them with a warning in the flasher that they break stuff.

SlimeVR-Firmware-WebBuilder/src/github/github.service.ts

Lines 119 to 122 in 2d09936

	return (
	semver.satisfies(version, '>=0.2.3') &&
	!semver.satisfies(version, '0.5.0 - 0.5.2')
	);

Not sure if the issue is right here or if it belongs to SlimeVR Server
