Mention 'Reset Empty Clipboard' Command in Wayland FAQ

For some time I've been wondering why I could paste from copyq's tabs but not with ctrl+v. TIL that it is because Wayland clears the clipboard when the owner of the clip exits. For example, this happens every time I take a screenshot, because the screenshot app exits immediately.

I found that a workaround for this is to use the 'Reset Empty Clipboard' Command and it works just fine. I feel like since this is basically required for Wayland, it would be worth a mention in the FAQ

Thanks!
