docs(Subject): Document changes to Subject.create

[rgbkrk]

Guide those migrating from RxJS 4 who are using Subject.create to
let them know about the new argument ordering.

Actually, it looks like we have the arguments reversed. It should be Subject.create(subscriber, observable), because Subscriber is an Observer. :\

@trxcllnt, I think you implemented this one, is there a reason for the reversal of argument order here?

[trxcllnt]

@Blesh no, just typed it that way a while back and it stuck.

Seems it's clarified and we can introduce changes to interface actually, so I have filed #1285 to track those and closing this PR. @rgbkrk , huge appreciate to catch this and take effort to bring PR for those - let's track root reason via filed issue. Thanks again!

[rgbkrk]

Thanks for tackling this.
