Add pre-built binaries to https://github.com/crc-org/crc/releases

We are slowly moving away from our tray, we'll need to offer an alternative way to get our binaries at some point.
Even without taking into account the tray, having 'community' builds would be useful. In my opinion they make sense to have on https://github.com/crc-org/crc/releases but we could arrange something else.

We could upload the binaries generated from our rpm, but they are not standalone because of some version.IsInstaller() checks preventing them to automatically download the binaries they need, see

crc/pkg/crc/preflight/preflight_checks_darwin.go

Lines 52 to 67 in 641ff18

	func fixVfkitInstallation() error {
	if version.IsInstaller() {
	return nil
	}
	h := cache.NewVfkitCache()
	logging.Debugf("Installing %s", h.GetExecutableName())
	if err := h.EnsureIsCached(); err != nil {
	return fmt.Errorf("Unable to download %s : %v", h.GetExecutableName(), err)
	}
	return nil
	}

for example.

Another option would be to build through github actions.

Later we could also focus on packaging it for homebrew, chocolatey and rpms, debs this'd provide better install/upgrade experience

Yeah, homebrew availability would definitely be great to have. For macOS, we can do both, github.com/crc-org/crc/releases and homebrew
