How to specify numpydoc_validation_checks from CLI

From the docs it is not clear if this is possible and my first tries failed.

If I do python -m numpydoc -hI see,

Implementing `python -m numpydoc` functionality.

positional arguments:
  import_path           e.g. numpy.ndarray

options:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        key=val where val will be parsed by literal_eval, e.g. -c use_plots=True. Multiple -c can be used.
  --validate            validate the object and report errors

and from the docs I see e.g. the numpydoc_use_plots configuration option mentioned in the help example.

I would like to specify the equivalent of e.g. numpydoc_validation_checks = {"all", "GL01", "GL02", "GL05"} - is this possible?

If not it should be explained, if yes I think there should be more examples of usage.

I tried e.g.,

python -m numpydoc -c numpydoc_validation_checks=all -c numpydoc_validation_checks=GL01 -c numpydoc_validation_checks=GL02 -c numpydoc_validation_checks=GL05 --validate test_module.good_docstring

and

python -m numpydoc -c numpydoc_validation_checks{"all", "GL01", "GL02", "GL05"} --validate test_module.good_docstring

Start with the configuration section of the linked installation docs and run python -m numpydoc -h to compare the documented and actual CLI syntax. Determine whether numpydoc_validation_checks can be supplied through -c; done means documenting the supported form with an example or clearly explaining that it is unavailable.
