Remove references to listenForBind batch argument

listenForBind only takes a single argument, but the documentation mentions a second "batch size" argument.

catalyst/src/bind.ts

Line 19 in c07f507

export function listenForBind(el: Node = document): Subscription {

👍 thanks @joshmgross!

I'm thinking it might be useful to remove listenForBind entirely from the docs; it's something Catalyst should manage internally, but we're not quite sure how yet. When we reach 1.0 we certainly won't document it.
