F-Droid publishing

Follow-up for suddenly disappeared #2246

@IzzySoft are you going to publish zxtune packages in your repo? AFAIR, the only issue was weak signature, but for now I have no ability to update it. It will be rotated for all the flavors after AGP support

Key rotation is possible of course – since Android 9. I don't know what the minimum Android version is your app supports, as there are no APKs I cannot check (and without APKs we also cannot add the app to IzzyOnDroid; there are no releases here in the repo). I'd say it's better to have a clean start. Key rotation is rather an "emergency solution", and not all F-Droid clients support it properly.
