Add Tabs component page

[aminalhazwani]

Vicky has been working on the draft for the Tabs component, here a google doc summary: https://docs.google.com/document/d/1jfFM9xb_meKTQJBacPvjMGAr_xg-d91m-ZVI9mfjWyw/

The main questions are:

• Usage: Difference between tabs and navs
• Style: Resemble index cards or sleek approach
  • Considering also potential mobile use
• Overflow behavior: Scroll, overflow menu, or flexible width?

@brassy- @shorlander Feel free to leave comments in the doc so that Vicky knows how to proceed, thank you very much!
