GraphQL, gql template literals, and including fragments

[baerrach]

Currently I am writing my graphql in a *.js file, where the query is referencing the fragment from a JavaScript variable that contains the fragment gql. However prettier doesn't recognise the ${} stuff and isn't reformatting the code.

Its entirely possible I'm not doing this in the recommended way (e.g. not using *.graphql files). Updates to existing documentation to put people on the right path would be appreciated.

fragments {
  all: gql`...`,
};

query = gql`
query allPartsByManufacturerName(
  $name: String!
) {
  allParts(filter:{
    manufacturer: {
      name: $name
    }
  }) {
    ...PartAll
  }
}
${fragments.all}

We don't currently support expressions inside tagged template GraphQL literals. We should add this.
