Summary:
Before 24w18a channeling tridents summoned a lightning bolt when thrown at players that are in creative mode. As of 24w18a this no longer works. May be intentional.

Steps to reproduce:

1. Obtain a trident enchanted with channeling.
2. Thrown it upward to make it so that it hits you in creative mode (it needs to be in your mainhand due to MC-271629 and MC-271533).
3. Move to make sure that the trident hits you instead of landing next to you.

Observed result:
When the trident hits you, no lightning bolt is spawned.

Expected result:
When the trident hits you, a lightning bolt should be spawned just like in 1.20.6.
