The swagger docs don't work when the browser cannot access the CDN for swagger js dependencies.

Is it possible to configure a custom CDN or serve the dependencies using static files as detailed here: https://fastapi.tiangolo.com/how-to/custom-docs-ui-assets/

Happy to provide effort to make any changes
