- Remove non-core rules (vue, ts, eslint-comments, eslint-plugin, node, prettier)

- Remove all configs except as needed to cover project-defined rules
- Testing: Change from broken use of "category" to relying on custom `meta.version` for determination of ES version (eslint docs allowing for customization within `meta`)
- Linting as per latest prettier
- Update devDeps

-- handle the `.eslintrc.js` file as a Node.js script.
-- handle the `webpack.config.js` file as a Node.js script.

 - [@mysticatea/block-scoped-var](docs/rules/block-scoped-var.md) handles variables which are declared by `var` declaration as block-scoped. It disallows redeclarations, uses from outside of the scope, shadowing.
 - [@mysticatea/no-instanceof-array](docs/rules/no-instanceof-array.md) disallows 'instanceof' for Array (fixable).

-> **Q:** Why don't you use those plugins directly?<br>
-> **A:** The combination with shareable configs and plugins has some problems because shareable configs were not designed to be used with plugins. @nzakas illustrated a way to use plugins as shareable configs together with other plugins in the discussion [eslint/eslint#3458](https://github.com/eslint/eslint/issues/3458#issuecomment-257161846). This is the way.
