###Description
Updates the contributor style guide to use array_like instead of array-like, matching NumPy terminology.

This changes the descriptor list and the example docstring in the same file.

###Notes
No tests were added because this is a documentation-only change.

No API reference files were changed because this does not modify the public API.

###Checks

• git diff --check

Thanks! I’ve reviewed the contributing guidelines and checked the change for accuracy.This PR only updates the style guide wording from 'array-like' to 'array_like' to match the terminology discussed in #765.

@manav252 we'll live with both 'array-like' and 'array_like' for now, as there are many instances of both terms. The numpy documentation has the same split personality. Thanks for the offer.
