Add Python fractions as a natively supported type

Initial Checks

• I have searched Google & GitHub for similar requests and couldn't find anything
• I have read and followed the docs and still think this feature is missing

Description

Hi,

Python fractions belongs to the standard library and that would be great to have is as natively supported type.

Is there another way to implement it ? Using validators and serializers ?

Thanks for your help!

Affected Components

• Compatibility between releases
• Data validation/parsing
• Data serialization - .model_dump() and .model_dump_json()
• JSON Schema
• Dataclasses
• Model Config
• Field Types - adding or changing a particular data type
• Function validation decorator
• Generic Models
• Other Model behaviour - model_construct(), pickling, private attributes, ORM mode
• Plugins and integration with other tools - mypy, FastAPI, python-devtools, Hypothesis, VS Code, PyCharm, etc.

Hi @etienne-monier,

Seems like a great feature request, and sort of goes along with the complex number support request. PRs welcome - we'd want to add support in pydantic first, but probably add support in pydantic-core eventually!
