Map Django's EmailField to OpenAPI string format `email`

[Zerotask]

Is your feature request related to a problem? Please describe. If you have a model which defines an EmailField, the generated OpenAPI specification is displayed as: email string <= 254 characters

If you manually define this email field as email: pydantic.EmailStr in your schema, it will be displayed as: email string email

So in this case, the string format email is used: https://swagger.io/docs/specification/v3_0/data-models/data-types/#strings

Describe the solution you'd like

Automatically map Django's EmailField to OpenAPI string format email

There are probably other Django field classes, which could be enhanced with string formats to be more precise

I noticed the same issue with Django's URLField, which is displayed as a regular string, but if you annotate it with pydantic.HttpUrl in your schema, it will be displayed with the OpenAPI string format uri
