Publish a winget package

Would be great if I could do winget install k0sctl. No idea what's needed for that, tho 👼

• Add k0sproject.k0sctl 0.28.0 microsoft/winget-pkgs#351126

I think at least at some point there was a chocolatey recipe, but I haven't been following what Windows people use now.

At least winget is what I use. Since it's endorsed and maintained by Microsoft, I think it makes sense to have it. (Also because it's darn simple to just have a package for the binary on the GitHub release pages.)

Not sure how to automate version bumps, though. Do they have their own mechanism, or do we need something in k0sproject which takes carte of that.
