Adding method chaining section on ActiveRecord querying guide [ci skip]

A better alternative to #17750

Thank you for the pull request.

I believe the same answer still applies here #17750 (comment).

Why do we need to talk about this for join but not for all, where or any method that returns a collection?

@rafaelfranca Is there a better place to put this?

Joining to find a single record is a common need (I think). I thought in putting this in the guides because I had this doubt in the past. The guides do not cover this until now.

I think someone needing to use find with where or all is not much common.

It is far more common that using with join. Chaining Active Record finders is something that should be documented independent of which finder method is being used since it applies to a huge number of methods.

If we are going to document such thing we should document as a new section and not in a specific use case.
