Only the post requests had /events/ added to them for V2 it seems. Getting orders should still be just fine without the update

Also the request input changed, the order data dictionary should look like this now:

        order_data: dict = {
            "ticker": ticker_str,
            "side": v2_side,
            "count": count_fp,
            "price": f"{yes_price:.4f}",
        }
        ```
        instead of:
        ```
      order_data: dict = {
            "ticker": ticker_str,
            "action": action.value,
            "side": side.value,
            "count_fp": count_fp,
            "yes_price_dollars": yes_price_dollars,
        }
        ```

but yes, getting orders should still be correct. Just placing orders fails
