Replace deprecated Pydantic call

[ogenstad]

Why

When you run "pytest test/unit" there's deprecation warnings regarding the use of the replaced method from Pydantic.

  /Users/patrick/Code/opsmill/infrahub-sdk-python/docs/docs_generation/helpers.py:21: PydanticDeprecatedSince211: Accessing the 'model_fields' attribute on the instance is deprecated. Instead, you should access this attribute from the model class. Deprecated in Pydantic V2.11 to be removed in V3.0.
    for field_name, field in settings.model_fields.items():

Walkthrough

A modification was made to the get_env_vars() function in docs/docs_generation/helpers.py. The change updates the function to iterate over ConfigBase.model_fields (class-level fields) rather than settings.model_fields (instance-level fields) when extracting field environment-variable mappings through EnvSettingsSource._extract_field_info. The extraction logic and output structure remain unchanged. This constitutes a single line modification with no impact to exported or public entities.
