Lots of UserWarnings for Unknown Section despite GL06 rule exemption

[Zeitsperre]

Hi there,

I'm wondering what the best way forward is for my use case. I currently make use of the module-level docstrings to supply the documentation on my project's ReadTheDocs page. This can include adding sections that are not in the standard.

Ignoring GL06/Unknown Section should be enough to handle this, but I still end up with many UserWarning messages when running the tool, e.g.

/pc/clone/_SwdT2XXRaOD_6gJ7rZXAA/py_env-python3/lib/python3.12/site-packages/numpydoc/docscrape.py:421: UserWarning: Unknown section Calendar Handling Utilities
  self[section] = content
/pc/clone/_SwdT2XXRaOD_6gJ7rZXAA/py_env-python3/lib/python3.12/site-packages/numpydoc/docscrape.py:421: UserWarning: Unknown section Cf-convention Checking
  self[section] = content
/pc/clone/_SwdT2XXRaOD_6gJ7rZXAA/py_env-python3/lib/python3.12/site-packages/numpydoc/docscrape.py:421: UserWarning: Unknown section Data Checks
  self[section] = content
/pc/clone/_SwdT2XXRaOD_6gJ7rZXAA/py_env-python3/lib/python3.12/site-packages/numpydoc/docscrape.py:421: UserWarning: Unknown section Data Flags
  self[section] = content
/pc/clone/_SwdT2XXRaOD_6gJ7rZXAA/py_env-python3/lib/python3.12/site-packages/numpydoc/docscrape.py:421: UserWarning: Unknown section Formatting Utilities For Indicators

/pc/clone/_SwdT2XXRaOD_6gJ7rZXAA/py_env-python3/lib/python3.12/site-packages/numpydoc/docscrape.py:421: UserWarning: Unknown section Indicator Utilities
  self[section] = content
/pc/clone/_SwdT2XXRaOD_6gJ7rZXAA/py_env-python3/lib/python3.12/site-packages/numpydoc/docscrape.py:421: UserWarning: Unknown section Dictionary And Yaml Parser

...

It would be great if ignoring GL06 would also prevent these UserWarnings from being emitted.
