Invalid test for list-style-type CSS property values

[foolip]

Reported by @jugglinmike in foolip/mdn-bcd-collector#2347:

The "harness" test for CSS property values uses the CSS.supports function where available. This is not a reliable way to test support for list-style-type values because that CSS property accepts any arbitrary string value.

This is apparent in the data for Chrome stored in the mdn-bcd-results repository: the results for the value "afar" are true for versions 1 through 44, false for versions 45 through 90, and then true again for versions 91 through 105.

The update-bcd script does not reflect this history in BCD due to a known deficiency.

Looking at https://mdn-bcd-collector.gooborg.com/tests/css/properties/list-style-type this does still seem to be an issue.
