doc: remove http2 pushStream weight option

Browse Source 
The PRIORITY field is only supported by HTTP/2 in a HEADERS frame
initiated by the client, not in a push request sent by the server.

Documents the recommended approach to set a silent priority as
used internally by nghttp2.

Setting the weight of a push stream is not allowed in the `HEADERS` frame. Pass
a `weight` value to `http2stream.priority` with the `silent` option set to
`true` to enable server-side bandwidth balancing between concurrent streams.
