css_ref broken links

[estelle]

What information was incorrect, unhelpful, or incomplete?

https://developer.mozilla.org/en-US/docs/Web/CSS/Reference#index, created with a macro call to {{css_ref}} lists pages as missing even though they are documented.

color-mix(), ::cue, :has, :is, layer, :where(), and many other pages in red do exist

some are in subdirectories (https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/color-mix, https://developer.mozilla.org/en-US/docs/Web/CSS/@import/layer_function)
others have parenthesis that aren't in the slug (https://developer.mozilla.org/en-US/docs/Web/CSS/:has, https://developer.mozilla.org/en-US/docs/Web/CSS/:is, https://developer.mozilla.org/en-US/docs/Web/CSS/:where)

@fiji-flo Could this be fixed by adding css/functions.json to MDNDataFiles, and using the mdn_url from there? I guess the current color-mix() entry comes from css/syntaxes.json, which doesn't have mdn_url context.
