Chrome 28 / Safari 9 support counter-increment CSS property (#25308)

This PR updates and corrects version values for Chrome and Safari for the `counter-increment` CSS property. The data comes from the [mdn-bcd-collector](https://mdn-bcd-collector.gooborg.com) project (v10.12.7).

Tests Used: https://mdn-bcd-collector.gooborg.com/tests/css/properties/counter-increment

Additional Notes: Safari 9 was guesstimated from lack of support in Safari 8 and support in Safari 9.1.
