>Description:
	In pkgsrc-current when trying to use devel/py-requests there is a warning printed:

	    /usr/pkg/lib/python3.10/site-packages/requests/__init__.py:102: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (5.0.0)/charset_normalizer (2.0.12) doesn't match a supported version!
	      warnings.warn("urllib3 ({}) or chardet ({})/charset_normalizer ({}) doesn't match a supported "
>How-To-Repeat:
	Just importing requests trigger this problem:

	$ python3.10 -c 'import requests'
	/usr/pkg/lib/python3.10/site-packages/requests/__init__.py:102: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (5.0.0)/charset_normalizer (2.0.12) doesn't match a supported version!
	  warnings.warn("urllib3 ({}) or chardet ({})/charset_normalizer ({}) doesn't match a supported "
>Fix:
	Probably devel/py-requests should be updated to the latest stable
	version that supports newer chardet. However, due requests-2.72.1 being
	the latest release supporting Python 2.7 we should probably also do the
	versioned Python dance (i.e. preserve that requests version too).
