column-pseudo not linked to BCD, showing incorrect support

[rviscomi]

As you can see in the web features explorer, the column-pseudo feature is reported to have no browser support and no MDN documentation:

However, there is an MDN page for this feature, and it shows support in Chrome/Edge 135:

It seems that column-pseudo.yml isn't associated with its corresponding BCD key(s). Likewise, css/selectors/column.json on BCD isn't associated with its corresponding web-features ID. Without this linkage, the feature isn't showing the correct browser support info.

Should this be fixed on the web-features side by adding the BCD keys, or on the BCD side by adding the web-features ID?

Let's add the BCD keys to web-features. Later, they'll get moved over to BCD as tags as part of the sync script.
