Add entry about E2EE of calls in Riot FAQ #57
Description
I was surprised not to find on the Web whether Riot calls were E2EE until I asked about it on #riot-web. I suggest adding an entry such as the following to the end-to-end encryption section of the Riot FAQ, assuming it is correct:
Are Riot calls end-to-end encrypted?
Audio and video calls are end-to-end encrypted in one-to-one chats with end-to-end encryption enabled (the number of devices doesn't matter).
End-to-end encryption of calls is not supported in group rooms.
