Add eslint checks for graphql files

[Roaring30s]

Is your feature request related to a problem?

Whenever I run npx eslint <files>, I am starting to get warnings.

Describe the solution you'd like

If team feels this is something that needs fixed, we could:

1. npm install --save-dev @graphql-eslint/eslint-plugin

2. Add a new override section to the .eslintrc.json (or equivalent config file) specifically for *.graphql files to use the graphql parser and plugins.
