Missing autocomplete and syntax highlighting for newer CSS properties

[florianbuehler]

Currently autocomplete and syntax highlighting is not working for some newer CSS properties (e.g. accent-color, ascent-override, descent-override, line-gap-overrideandsize-adjust`.)

The autocomplete will be fixed with PR #333.

However the syntax highlighting depends on https://github.com/microsoft/vscode/blob/main/extensions/css/syntaxes/css.tmLanguage.json which again depends on https://github.com/atom/language-css/blob/master/grammars/css.cson.

So we are dependend, that they adapt their css grammar.

@florianbuehler ive just tested this in a native css file and there's no syntax highlighting there either. So it looks like https://github.com/microsoft/vscode/blob/main/extensions/css/syntaxes/css.tmLanguage.json hasn't updated yet. Maybe when that updates it will just work here too.

You probably need to raise this further upstream.
microsoft/vscode#132199 which is waiting on atom/language-css#184

[florianbuehler]

@jasonwilliams, you are right. I also raised it upstream. (issue and fix).

However there was already a pull request to fix the accent-color (but not the other CSS properties) quite some time ago but nothing happened till now.
