consider removing now dependencies?

[muhajirdev]

now is quite heavy as it downloads the binary, as the result trying is a little pain. Also it has problem with yarn (vercel/vercel#602). I my self didn't install now with yarn, but do install other global package with yarn.

Further more, why install now locally?

To make it easier for beginners to get started and get something up in the cloud really quickly.

But I agree that it's a rather heavy dependency, which might not be used that often. But currently it's a part of our contentful guide which means we can't drop it right away.
