Server notice do not support `format` & `formatted_body`

[dedfaf]

In server_notice.go#L39 with only MsgType & Body defined, format & formatted_body are discarded, so format in server notice is unsupported.

dendrite/clientapi/routing/server_notices.go

Lines 37 to 45 in e546df2

	type sendServerNoticeRequest struct {
	UserID string `json:"user_id,omitempty"`
	Content struct {
	MsgType string `json:"msgtype,omitempty"`
	Body string `json:"body,omitempty"`
	} `json:"content,omitempty"`
	Type string `json:"type,omitempty"`
	StateKey string `json:"state_key,omitempty"`
	}

In synapse, this is handled by

async def send_notice(
        self,
        user_id: str,
        event_content: dict,
        type: str = EventTypes.Message,
        state_key: Optional[str] = None,
        txn_id: Optional[str] = None,
    )

By replacing dendrite's content definition to Content map[string]interface{} json:"content,omitempty"`` would also support format in server notices. Check dedfaf@3c528cb. Or we could just add format & `formatted_body` field..

Note that matrix spec have msgtype & body defined only, so this is not part of matrix spec for now.

I could made a PR if the change is ok, but im not sure whether this should or not be an implement.

Sorry to say this, but that's why this won't get any further attention from my side. If even Synapse can't follow the spec, where do we end up?

May we change directions and let Synapse implement Dendrite behavior?
