Update CSS accent-color spec URL (#11514)
Update CSS accent-color spec URL (#11514)

For spec URLs, one of the practices we’ve been following is to prefer
un-leveled (un-versioned) spec URLs.

So, for example, https://drafts.csswg.org/css-ui/#widget-accent
rather than https://drafts.csswg.org/css-ui-4/#widget-accent.

The exception to that rule is the case of spec URLs such as
https://drafts.csswg.org/css-color-5/#color-mix — that is, spec URLs
for any features that are not in the un-leveled spec, but instead only
in a leveled version.
