False warnings for stroke-opacity

[ryo-manba]

stroke-opacity generates false warnings due to incorrect syntax, as it doesn’t handle percentages.
See: stylelint/stylelint#8080 (comment)

Version 2.11 of mdn-data has updated definitions for stroke-related properties (see mdn/data#757).
Updating mdn-data and removing the corresponding patch should fix this issue.

The fix in mdn/data is incorrect: the spec defines <'stroke-opacity'> as <'opacity'> (syntax of the opacity property) not <opacity> (a non-exists syntax definition). I changed CSSTree's patch, the issue should be resolved.

I created a PR in mdn/data.
