   If we don't support Server Push on origin side for now, we need to indicate it by sending SETTINGS_ENABLE_PUSH:0.
   
   > SETTINGS_ENABLE_PUSH (0x02):  This setting can be used to enable or
         disable server push.  A server MUST NOT send a PUSH_PROMISE frame
         if it receives this parameter set to a value of 0; see
         [Section 8.4](https://datatracker.ietf.org/doc/html/rfc9113#section-8.4).  A client that has both set this parameter to 0 and
         had it acknowledged MUST treat the receipt of a PUSH_PROMISE frame
         as a connection error ([Section 5.4.1](https://datatracker.ietf.org/doc/html/rfc9113#section-5.4.1)) of type PROTOCOL_ERROR.
   
   >  The initial value of SETTINGS_ENABLE_PUSH is 1.  For a client,
         this value indicates that it is willing to receive PUSH_PROMISE
         frames.
