As part of our efforts to migrate PageTriage to Vue.js, we want to take a piecemeal approach to converting the Curation Toolbar - going one component at a time.

This task covers conversion of the Article Info component:

• ./modules/ext.pageTriage.toolbar/articleInfo.js
• ./modules/ext.pageTriage.toolbar/articleInfo.less
• ./modules/ext.pageTriage.toolbar/articleInfo.underscore
• ./modules/ext.pageTriage.toolbar/articleInfoHistory.underscore

Acceptance criteria:

• duplicates current behavior, with the possible exception of bug fixes
• as similar as possible to current style as possible
• protected by pagetriage_ui=info url parameter feature flag
• uses common flyout code T376103
• uses updated toolIcon code T376101
