fix: Missing syntax highlighting for css partials in FAST tagged templates extension

[KingOfTac]

🐛 Bug Report

The FAST Tagged Template Literals vscode extension doesn't recognize css.partial for syntax highlighting.

🤔 Expected Behavior

css.partial should be recognized for syntax highlighting

😯 Current Behavior

css.partial does not have syntax highlighting.

💁 Possible Solution

I think this line would need to include partials in some way. (not a regex expert)

As a workaround css.partial/* css */ will enable the syntax highlighting but it gets tedious.
