Storybook - automate deployment

[zavelevsky]

We need to automate our storybook deployment. Currently it's manual in part, by updating the repo: https://github.com/bancorprotocol/storybook

We can add a github action that copies the output to this repo and merges to main.
We can also solve it as part of the move to S3 - where we will just publish the storybook folder to another bucket.

A few pointers for the first option:
