Feat: Add support for .gql files

[chrskerr]

We are running a patched version of this package (it was less work than renaming all of our .gql files to .graphql) without any problems, so am sharing upstream in case you'd like to merge it in!

Cheers Chris

Thank you for the PR! It looks like CI didn't run due to a misconfiguration on the repo. Today I updated CI so that CI would run for fork PRs as expected.

I ended up picking the change from here into another PR. There were a few tiny things that needed changing for it to be added:

• The change needed to be in the src code (and then yarn build run to generate the lib files)
• The commits need to be commitizen compliant

(These would have popped up in this PR if CI had been running correctly.)

Anyways, your change is in! It's been released in 3.8.0.

Thank you for the contribution!
