1.20.5 (#127)

* 23w51b

* make recalculate_near_end_of_path public

so other plugins can do .after(recalculate_near_end_of_path)

* update to 24w03a i think

* start implementing 24w13a

* registries work (but a lot of packets are still broken)

* fix recipes and commands packets

* i love codecs :D i am not going insane :D mojang's java is very readable :D

* item components are "implemented" meowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeowmeow

* update to 1.20.5-pre3

* fix all the broken packets and clippy (mojang please don't do an update like this again or i will murder someone)

* 1.20.5-rc1

* fix failing tests

* 1.20.5
