What this PR does?
Add AntDesigns to list of CSS Frameworks.

Why are you adding given library? (Short description why do you think that this library is important)
AntDesign is a great design alternative for React. It has many components and is constantly updated. Its brightness is in forms, which have their data-binding using redux.

IMO AntDesign is better than bootstrap to work with React. A great addition indeed.

Agree that is better to work with React, but I don't agree that is a good to know library, more like possibility, because very few projects are using Ant Design. There is a lot of projects ported from not React versions and therefore were built with bootstrap.

Ant Design growth is steady 👍 :

I think, that there should be a separation of CSS frameworks that have or do not integrate with React. This helps a lot in choosing the CSS framework.

Ant Design is superior, because it's not just a UI library.
