* Spiderlings can cross webs (#75404)
## About The Pull Request
Reliable web traversal is now governed by a trait instead of a type
check.
Spiderlings have that trait.
## Why It's Good For The Game
Spiderlings are spiders and shouldn't get stuck in webs.
Turning this into a trait means that we can make more things apply the
trait in future if we want, without having to expand a list of allowed
mobs.
## Changelog
