[BUG] Field examples not showing in OpenAPI docs

[Zerotask]

Describe the bug

Example:

class OrganizationPostSchema(Schema):
    email: EmailStr | None = Field(default=None, examples=["[email protected]"])

it does not show in the generated OpenAPI docs.
Although I noticed that you can pass it as:

class OrganizationPostSchema(Schema):
    email: EmailStr | None = Field(default=None, example="[email protected]")

This will show it like this:

But example is not a valid parameter for Pydantic's Field class.
Therefore the IDE and mypy will show it as an error.

Versions (please complete the following information):

• Python version: 3.12
• Django version: 5.0.x
• Django-Ninja version: 1.3.0
• Pydantic version: 2.10.0

The preferred solution would be to display examples the same way as you do currently with example
