css.properties.column-rule-color - wrong spec and missing feature

What type of issue is this?

Missing compatibility data

What information was incorrect, unhelpful, or incomplete?

BCD is missing support for comma-separated values and the repeat() function.

The property is now defined in CSS gaps rather than multi-col.

This is true for column-rule color, style, and width.

What browsers does this problem apply to, if applicable?

MDN metadata

Start with the BCD entry queried as css.properties.column-rule-color and compare it with the MDN page and the CSS Gaps specification linked in the issue. Check how the related column-rule-color, column-rule-style, and column-rule-width data represent syntax, then update the compatibility data so the comma-separated values and repeat() function are reflected and validate it with bdc.
