hackney 4.8.5

Fixed

• A GOAWAY fails only the requests the server refused. HTTP/2 failed every
  in-flight request with {error, {goaway, _}}, including ones the server
  went on to complete, and HTTP/3 ignored the GOAWAY and kept sending new
  requests on the connection. Accepted streams now finish, streamed uploads
  and responses included, refused ones fail and are reset, and the
  connection leaves the pool and closes once drained (#961, #962, #964,
  #965, #968).
• A failed HTTP/2 request body send fails the other streams on the
  connection instead of leaving them waiting (#964).
• Closing an HTTP/3 connection no longer makes the other live HTTP/3
  connections unreachable. The connection table was owned by the first
  connection and went away with it (#967).

Changed

• Update h2 to 0.12.4, quic to 2.1.1 and webtransport to 0.4.8.
