client: Add dummy package.json for ESLint custom rules (#281)
* client: Add dummy package.json for ESLint custom rules
NPM requires "package.json" file to include "name" and "version" fields
for packages published to the registry [0]. ESLint custom rules will
stay within this repo for the time being. Dependabot doesn't impose any
requirements on this file so an empty one would suffice but let's provide
some details anyway.
File "index.js" now filters out all non-JS files so there's no attempt
made to pick up additional rules from the dummy "package.json".
