Sort JS imports in the EE code

What does this MR do?

Sort all imports by their groups. This is the 2nd MR from 4 to address the issue.

3rd MR will cover the EE specs.

Example

Without path group this order considered as valid

import { GlIcon } from '@gitlab/ui';
import $ from 'jquery';
import '~/behaviors/markdown/render_gfm';
import { unescape } from 'lodash';
import MarkdownHeader from './header.vue'; // not okay
import MarkdownToolbar from './toolbar.vue'; // not okay
import { deprecatedCreateFlash as Flash } from '~/flash';
import GLForm from '~/gl_form';
import axios from '~/lib/utils/axios_utils';
import { stripHtml } from '~/lib/utils/text_utility';
import { __, sprintf } from '~/locale';
import GlMentions from '~/vue_shared/components/gl_mentions.vue';
import Suggestions from '~/vue_shared/components/markdown/suggestions.vue';
import glFeatureFlagsMixin from '~/vue_shared/mixins/gl_feature_flags_mixin';

With path group this order will be transformed to

import { GlIcon } from '@gitlab/ui';
import $ from 'jquery';
import '~/behaviors/markdown/render_gfm';
import { unescape } from 'lodash';
import { deprecatedCreateFlash as Flash } from '~/flash';
import GLForm from '~/gl_form';
import axios from '~/lib/utils/axios_utils';
import { stripHtml } from '~/lib/utils/text_utility';
import { __, sprintf } from '~/locale';
import GlMentions from '~/vue_shared/components/gl_mentions.vue';
import Suggestions from '~/vue_shared/components/markdown/suggestions.vue';
import glFeatureFlagsMixin from '~/vue_shared/mixins/gl_feature_flags_mixin';
import MarkdownHeader from './header.vue';
import MarkdownToolbar from './toolbar.vue';
