Enums and other decls members have incorrect highlighting

Firstly, thanks for maintaining this library!

I think a recent change broke how declaration members are rendered. If you take a look at this snippet from swift-mmio you can see the enum cases are highlighted incorrectly:

Thanks for the report. There must be some changes I made that are not working with GitHub's highlighter, but are working fine with VS Code. 😢

I'll try to look into these soon but unfortunately GitHub only updates their grammars to the latest version every few months, so it may be a while before it's fixed.

I believe this is an error with GitHub's highlighter; you can follow along at: github-linguist/linguist#6668

The underlying issue with GitHub has been fixed. Sadly, GitHub is no longer using this tmLanguage grammar: github-linguist/linguist#6668 (comment)

Regardless of them switching over, truly thank you for keeping this grammar alive, it's been very helpful. I appreciate the time and effort you've put into making this :)
