With experimentalRustCrypto: true, Draupnir 2.9.0 exits on startup with
"Encryption not possible: server not revealing device ID": its access
token is not bound to a device, which matrix-bot-sdk crypto requires.
Restores experimentalRustCrypto: false so the deploy hook brings it back.
To enable encryption later, give Draupnir a device-bound access token
(a normal password login) first.
