Fix Eslint config so that it uses rules from .prettierrc

[XEQTIONR]

This enables editors (like VSCode) to check for rules present in .prettierrc and flag violations inline in file editors.

Prettier documentation discourages doing that.
https://prettier.io/docs/integrating-with-linters#notes
I can also add my 2 cents, that it's basically always better to have format on save in the preferred editor or use pre-commit hooks.

Thanks, guys. I agree, @XEQTIONR. This seems like something that not everyone may need in their project, and the fact that Prettier generally does not recommend it is a good enough sign not to include this by default.

Thanks!
