I was testing the PR #3909 and noticed it only accepts .graphql files and since it's a very common practice to use .gql files for shorter typing I added support for those by changing the test for graphql files to the one here: https://github.com/apollographql/graphql-tag#webpack-preprocessing-with-graphql-tagloader
Also added a test for the gql extension and ran prettier.
Let me know any problems or if it's not something you don't plan to support
