Updated BookingCard.md to render component successfully

Updated BookingCard's readme

Description

The documentation for the BookingCard component was incomplete. On rendering the component in the index.js file inside the pages folder, there was an error of not recognizing icons in the props. I tried to understand the BookingCard/index.js and BookingCard.stories.js files but could not find any issue there. On importing the icons file in the pages/index.js, the error was resolved.
