Re: [csswg-drafts] [css-values-4] Clarify that function component values need to be followed by parentheses (#5728)

Parens in non-terminals are just a way to implicitly refer to the grammar of the given function, like `<'color'>` refers to the 'color' property. It's not meant to be a general policy one way or the other.

Things like `<url>` aren't referring to the `url()` function, they're referring to anything that represents a URL, which can also be a `<string>`.
