Chore: remove unnecessary ignore pattern from internal js linting (#154)
Chore: remove unnecessary ignore pattern from internal js linting (#154)

This ignore pattern is no longer necessary (ESLint lints .eslintrc.js as of [ESLint 7](https://eslint.org/blog/2020/05/eslint-v7.0.0-released)), and it was causing ESLint to lint some files in node_modules for me locally.
