ci(.github/workflows/storybook): create workflow to always merge `mai…

…n` -> `storybook` branch

The `storybook` branch will now be a permanent fixture alongside `main`. Its purpose is to deploy to
a separate URL on Vercel so we can host the docs and `storybook` output simultaneously, since
`next.js` cannot deploy static HTML found in `storybook` output.
