This is a pretty big update with some nice functionality

- Bug fix for forms schema (62) and finally some [documentation about form data](https://django-ninja.rest-framework.com/tutorial/form-params/)
- Local swagger JS bundle (14) - Now if you put `ninja` to INSTALLED_APPS - local bundle will be used, otherwise js will be loaded from CDN
