feat: add skeleton component

Skeleton component to show in a loading state while resolving data or promise

[The-x-35]

I have taken part in the foss hack event and request you to assign this issue to me under the event.
My approach to solve this issue would be to add the skeleton component as a new component in the src/components folder and then add the related story to it in the stories folder and then test the code. I will use the shadcn skeleton component for reference and will try to show the basic placeholder for the component being loaded.
If there is anything more I need to do please guide me.
