Update babel.md since Babel does not recommend babelrc

[dospore]

What I did

Just a little one but just updated the documentation under the Babel docs since Babel does not recommend babelrc, babel recommends babel.config.js. Happy to change wording here but just chose something off the top of my head.

@jonniebigodes I dont know why I was thinking about this but I re-read the docs and I am not sure I am certain. So its up to the maintainers if you want to change. Babel itself uses babel.config.js but as per the docs I linked in the PR I think its "If Guy Fieri is your hero? We recommend using the babel.config.json format." lmao

@dospore sorry for the delayed response on this. We've been busy here at Storybook. Hope you don't mind, but I'm going to close this as the team is working on some features related to Babel and that will require some additional changes to this documentation piece.

Hope you don't take it the wrong way and nonetheless, thank you so much for taking the time to put together this pull request and help us improve the documentation. We're thankful for it 🙏 !

Looking forward to seeing your next contribution. Hope you have a fantastic day.

Stay safe
