[BUG] Warning about BodyParams shadowing BodyModel

[pmdevita]

Describe the bug
A clear and concise description of what the bug is.

Got this warning

/usr/local/lib/python3.12/site-packages/pydantic/_internal/_fields.py:201 UserWarning: Field name "schema" in "BodyParams" shadows an attribute in parent "BodyModel"
warnings.warn(

At a quick glance, this seems to have something to do with the OpenAPI spec generation, given references in our tests.

Versions (please complete the following information):

• Python version: 3.12
• Django version: 5.2
• Django-Ninja version: using the 1.4.0 performance branch
• Pydantic version: 2.8

Note you can quickly get this by runninng in ./manage.py shell this line:

import django; import pydantic; import ninja; django.__version__; ninja.__version__; pydantic.__version__

Did some more digging, this seems to be an error specific to one of my projects

@router.patch(
    "{uuid:obj_id}",
    response={204: None},
)
def patch_obj(
    request: HttpRequest, schema: MyObjSchema
) -> tuple[int, None]:
    ...

Naming the parameter schema here causes the warning.

Should we have some higher level check to warn or explain this to the user? Or should we leave this as is?
