Add Windows on ARM release

[nikwen]

I've started using Windows 11 on arm64. It would be nice if we started releasing arm64 executables of Fiddle.

The x64 emulation is slow.

We actually purposely don't ship these at the moment, see #1071.

Goes back to an old unresolved issue (electron/update.electronjs.org#107) which caused the wrong arch to be downloaded during updates. Was easier to just remove WoA here, as the issue is still unresolved (AFAIK) on that repo.
