Checklist

Check all those that are applicable and complete.

• [ ] Merged with latest master branch

Please check the following use-cases once from design end:

• Disabled card should not be focusable
• Also, the card is not yet selected but still shows primary color focus ring

[anuradha9712]

Please check this once if we need a separate States story to display both disabled and default cards

[anuradha9712]

Please write a test case ensuring that user is not able to select/deselect disabled cards. Write test case for both single-select and multi-select cards.
