5 new icons, and some maintenance

We have added 5 new icons 🎉, in 3 sizes (16, 24 and 32px)!

List of the newcomers, including the requested drag-dots icon:

• CarLeft
• CarRight
• PlaneLand
• PlaneTakeOff
• DragDots

Additionally, these changes have been made on the code side of the repository:

• lingui files have been moved from individual icon directories to a separate locales directory: this is not a breaking change for users.
• added inline JSDoc typings to icon React components for improved autocomplete and prop hints in JavaScript editors — via user contribution! ⭐

You can see all available icons in our documentation here.
