add shortcut for running yarn storybook in cra-kitchen-sink

[Hypnosphi]

Before

cd examples/cra-kitchen-sink && yarn storybook

After

yarn start

[usulpro]

Great! It's a sort of script that I really wanted to have 👍

The only inconvenience for me that my terminal doesn't support auto filling yarn commands by [Tab]. And I will need to type it manually (while it works for paths). So, in this case, I'd prefer something shorter e.g. yarn start :)

Ok, renamed that

[usulpro]

Looks good to me!
(could you change script name in your first comment?)

[Hypnosphi]

Did that as well

Good first step, to making running the example(s) easier, thanks. Will be improving on this at a later stage! (we do have more examples 👍 )
