Add react moderation banner component

Break out `annotation-user` component from `annotation-header`

Rename group-list-v2 => group-list

Now that the old group list/menu has been removed, rename the new
version so that the file name matches the component name.

Always use main URL from main frame when searching for groups

Remove old dropdown menu implementation

Remove old groups menu and "community_groups" feature flag checks

This was used by the old dropdown menus.

The corresponding JS component was removed as part of the recent
redesign of the groups menu.

The new groups list implementation is still in `groups-list-v2.js`
rather than renaming the file to avoid the diff being too confusing.
Renaming it to remove the "-v2" suffix will happen in a follow-up
commit.

Use Prettier to auto-format .scss files

Merge removal of dropdown-menu-btn.scss

Convert and apply new menu styles, icons to annotation-publish component

- Add `z-index` to menu-content elements to make sure they are rendered
  on top of other sidebar elements
- Bump `z-index` on menu arrow so that it is above `menu-content`
