Full traceback

Expected behavior

Any section containing Attributes: should be removed when this flag is enabled.

Environment information

• System: Windows-11-10.0.22631-SP0
• Python: cpython 3.12.0b4 (C:\Users\Username\Repositories\reactpy-router.venv\Scripts\python.exe)
• Environment variables:
• Installed packages:
  • mkdocs v1.6.1
  • mkdocstrings v0.26.2
  • mkdocstrings-python v1.12.1
  • griffe v1.4.1

Additional context

Was attempting to use this to hide the docstring attributes.

To be honest I would have preferred to hide the section highlighted in red. There doesn't appear to be a convenient way of doing that at the moment.
