Corrected a grammar mistake in Stream documentation

[3674823674252]

This morning I was reading through the documentation on Streams and came across this sentence, which seemed not valid:

"If you supply as the second argument to the it will be passed to push method,.."

So I corrected it to:

"If you supply output as the second argument to the callback, it will be passed to push method,.."

That is the only change in this pull request.

Would you mind setting your git name to be your real name so this can be properly attributed? Presumably 3674823674252 isn't your real name. git config --global user.name "your name", then git commit --amend this one and force push it to your repo/v1.x branch and I believe that should update it.

That is my intentional username.. Corrected commit, the author is set to account with more "pronounced" username (that's my other account)

Sorry @3674823674252, I don't want to impose a "real names policy" here, its just that some times people are unaware that they have not properly set a username. It's ultimately your choice what you're called as long as its intentional.
