Floating anywhere like in water (1.21.5 to 1.21.8)

### I've searched existing issues and couldn't find a duplicate. - [x] I confirm this is not a duplicate. ### Operating System Window 11 ### Server Software Version/Commit Pumpkin 0.1.0-dev+26.2 (Commit: 0d44394/release) ### What happened? Basicly if you join any pumpkin server using 1.21.5 to 1.21.8 (maybe lower these ones I have found / test) the client or server thinks they are in water. When it thinks this it allows the client to just hold space and float up in the air like you was swimming in water, you crouch it also holds you in place. Doesn't take oxygen at all though. You also still take fall damage. ### To Reproduce Really easy Steps: - Join any Pumpkin server on client using 1.21.5 to 1.21.8 - Hold space and your done. ### Expected behavior You should just jumping up and down, which is the normal behavior you expect when holding space.
