Drop @babel/eslint-parser

@babel/eslint-parser does not parse correctly ES modules, throwing the following error:

> Parsing error: You appear to be using a native ECMAScript module configuration file, which is only supported when running Babel asynchronously or when using the Node.js `--experimental-require-module` flag

This error is thrown even with `sourceType` set to `module`.

Per @babel/eslint-parser README:

> You only need to use @babel/eslint-parser if you are using Babel to transform your code.

As the default parser does not cause this problem, so no reason to keep an extra dependency.
