Template string interpolation in comment breaks loaded graphql asset

[vctr-dev]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch graphql-import-loader@0.2.1 for the project I'm working on.

If there is a comment in the .graphql file e.g. ${FIELD} ${OPERATOR}..., this breaks the generated file as it would treat them as a string interpolation due to backticks being used to wrap the export.

My solution is to replace ${ with \${, since $ is a valid symbol in graphql.

Here is the diff that solved my problem:

diff --git a/node_modules/graphql-import-loader/dist/src/index.js b/node_modules/graphql-import-loader/dist/src/index.js
