* Configuring the player (i.e. sending resource packs) should now be done in the new PlayerConfigurationEvent.
* The new PlayerEnteredConfigurationEvent is called when a player acknowledged the switch to configuration state.
* The PlayerEnterConfigurationEvent is no longer called twice. It is now called when the backed wants to reconfigure the player.
* The PlayerFinishConfigurationEvent should no longer be used to configure the player (i.e. sending resource packs). This is because since 1.20.5 the backend server can't send keep alive packets between switching state anymore and the connection will thus time out.
* Send LoginAcknowledged immediately
* Resend player list header/footer after backend server switched to config state
* Fix clearHeaderAndFooter not clearing fields in ConnectedPlayer
* Clear boss bars, header/footer, tab list when switching client to config state
* Send client settings in config state
