* Convert tabs component to TypeScript
* Add tabs component story
* Add desciptions in comments to the Tab props
* Rename and export tabs component to display descriptions in Storybook
Renamed Tabs component to __Tabs as a sign it should not be used directly. Since we were using withInstanceId as the default export and were not exporting the Tabs component, Storybook could not retrieve the description and default values. We have renamed and exported the component to make sure Storybook can pick up the descriptions and default values.
* Rename exported Tabs component
Changed the exported Tabs component from __Tabs to __TabsWithoutInstanceId to make it more descriptive.
