Add example: filtered delete with in operator

[scotttrinh]

I was pairing with @DijanaPavlovic on doing this exact thing, and it took us both a few minutes to wrap our heads around this so thought it was worth adding an example to the docs.

Added a test to make sure I didn't screw this up!

Hey, @scotttrinh this is great... I'm just not sure what is the intent in general throughout the docs, there is delete inside QueryBuilder and Delete like a separate page with only one simple example... @raddevon

Yeah, I agree that it's confusing and could be cleaned up a lot. Maybe we move the "cheatsheet" examples into their respective top-level page? Seems like that's easier to reference then going to the bottom of the query builder docs.

Thoughts @raddevon

@scotttrinh @DijanaPavlovic I like the idea of moving the cheatsheet examples into their respective sections. I think our goal is to ultimately do something like that with all of the top-level cheatsheets (Guides > Cheatsheets) as well, so this would make the JS docs consistent with the rest once that effort is completed.
