Show updated relation reply from edited message - v2 (#6817) 

Part of https://github.com/vector-im/element-web/issues/10391

When `m.relates_to` -> `m.in_reply_to` is provided in `m.new_content`
for an edited message, use the updated reply.

ex.

```json
{
  "type": "m.room.message",
  "content": {
    "body": " * foo bar",
    "msgtype": "m.text",
    "m.new_content": {
      "body": "foo bar",
      "msgtype": "m.text",
      "m.relates_to": {
        "m.in_reply_to": {
          "event_id": "$qkjmFBTEc0VvfVyzq1CJuh1QZi_xDIgNEFjZ4Pq34og"
        }
      }
    },
    "m.relates_to": {
      "rel_type": "m.replace",
      "event_id": "$lX9MRe9ZTFOOvnU8PRVbvr1wqGtYvNQ1rSot-iUTN5k"
    }
  }
}
```
