Only widen the semver range for the graphql dependency of apollo.

Per the correct assessment of what we want from the `graphql` package within
the `apollo` package, in the following conversation:

#1078 (comment)

Specifically, we're okay using whatever 14.x version of `graphql` is
potentially already available to us when someone installs `apollo` into
their application's `devDependencies` in an existing application.

If the existing application doesn't already have a 14.x version of `graphql`
we will use the latest `14.x` version.

With any success, this will cl_ose #1078 automatically (and not just because
I said "close PR number" in this commit message!).
