Subject: [PATCH] uploadRoomKeysToBackup: Use V3 route

Fixes https://github.com/element-hq/hydrogen-web/issues/741

"Tested" locally by rewriting `r0` to `v3` in reverse proxy (Caddy) and seeing `All keys are backed up.` instead of repeated failing PUT requests towards Conduit (home server)

```
matrix.example.com {
    rewrite /_matrix/client/r0/room_keys/keys /_matrix/client/v3/room_keys/keys?{query}
    reverse_proxy /_matrix/* localhost:8448
}
```
