bug: Extension does not work when separate_signature is set to True [mkdocs]

[mmzeynalli]

Description of the bug

So, I had my docs already working. Added new pydantic models and saw that mkdocstrings cannot parse it correctly so I used this extension, but got really similar result.

To Reproduce

My config file:

plugins:
  - search
  - mkdocstrings:
      default_handler: python
      handlers:
        python:
          paths: [../../src]
          options:
            show_root_heading: true
            show_source: false
            show_if_no_docstring: true
            inherited_members: true
            members_order: source
            separate_signature: true
            unwrap_annotated: true
            filters:
            - '!^_'
            merge_init_into_class: true
            docstring_section_style: spacy
            signature_crossrefs: true
            show_symbol_type_heading: true
            show_symbol_type_toc: true
            extensions:
            - griffe_pydantic

Current behavior

The docstrings of fields are shown okay, however, it does not show the types of fields.

Expected behavior

If I comment out separate_signature: true, then everything is as expected:

Hi @mmzeynalli, thank you for the report. Could you actually provide some code that would allow me to replicate the issue you describe?

[mmzeynalli]

So, my Pydantic schemas is simple:

from urllib.parse import parse_qsl

from pydantic import BaseModel, model_validator

class CallbackDataSchema(BaseModel):
    """Raw və encoded callback data schema-sı"""

    data: str
    """Base64 formatında gələn data"""

    signature: str
    """EPOINT_PRIVATE_KEY"""

    @model_validator(mode='before')
    @classmethod
    def convert_str_to_dict(cls, data: bytes) -> dict:
        """Query string formatında gələn datanı düzgün formata çevirmək üçün funksiya"""
        return dict(parse_qsl(data.decode()))

I have provided my mkdocs.yml above, and in markdown file, I just "call": :::integrify.epoint.schemas.callback.CallbackDataSchema, with no extra options.

OK it was actually that mkdocstrings-python did not respect the show_signature_annotations option when rendering attribute signatures in headings. It now will!
