Add icons/folder-icons for different Storybook folders

Hi @miguelsolorio, I noticed that there are no folder icons for the Storybook and decided to add icons for it
I chose the color based on the logo of the Storybook itself and also by analogy added other icons that are associated with pink

Thanks for the PR, do you mind updating the description to include a screenshot?

Also, these appear to be generic folder/file icons. Did you intend to add Storybook versions?

Yes, I can add a screenshot of those folders later

Regarding generic folders, I tried to stick to the general style you specified (for example, if a file starts with ., the folder will have a circle in the lower right corner, like .vcode or .next).
Also I decided to add a couple of generic icons right away, because I saw similar variations for blue, green, and other colors (maybe they will come in handy in the future to describe some other files or folders).

I think this style of generic folders suits better than a folder with a storybook logo)
