Update peerDependencies to include qs

[jsjoeio]

Addresses issue apollographql/apollo-link-rest#187 (comment)

qs is a peer dependency needed by apollo-link-rest so this updates the official docs to reflect that.

TODO:

• Make sure all of new logic is covered by tests and passes linting
• Update CHANGELOG.md with your change

Good spot, thanks for taking time out of your day to fix this 💯

CircleCI ran out of memory... We'll probably need another push to rerun it, have no rights there.

[jsjoeio]

No problem! Credit goes to @escapiststupor for pointing this out

[JoviDeCroock]

I can push your changelog entry later tonight, or you can do so yourself if you so please. This will rerun CircleCI so we can merge it.

[jsjoeio]

I updated the CHANGELOG. Do you mind taking a look to make sure the formatting is okay?

I tried to match the previous entries as best I could.
