Migrate download menu in editor left menu to react (#10046)

* Initialize left menu react migration and migration download menu UI to react

* Add test case to DownloadMenu react component

* Update test description and add an href check to one of the download link

* Extract storybook document mock to its own fixture file

* Add mockCompileOnLoad config on storybook editor scope
  - if mockCompileOnLoad: true (default), then the default compile mock will be used
  - If mockCompileOnLoad: false, then we have to provide a compile mock on the storybook component

* Create download menu storybook component

* Use a single "editor-left-menu" controller on the editor left menu migrations

* Remove the form import from the react version of the left menu

* Change inline style to utility class name
