Remove import path order linting

What does this MR do?

This removes the import path order lint rule.

Previously, this would be disallowed by this rule:

import Vue, { nextTick } from 'vue';
import Mousetrap from 'mousetrap';

Because vue is alphabetically sorted after mousetrap. With this change, this order would be allowed.

Pros

• Our imports would no longer need to be sorted alphabetically according to their import paths 🤷

Cons

• Our imports would no longer need to be sorted alphabetically according to their import paths 🤷
• We spent quite a lot of time sorting our imports according to this rule; this would waste that effort.
