Fix SpatialPipeline with_predicate docs

[cBournhonesque]

Objective

The docs say that the ray/shape casts will stop on the first instance where the predicate returns false, but it seems like the opposite is the case.

Maybe it would be good to add a unit test to confirm this.

Thanks, yeah I think the docs for the predicates are currently wrong. I'm pretty sure the old callback docs are correct though.

Oh I see; I didn't test for callback but I assumed they were also inverted; will fix
