[csswg-drafts] [filter-effects-1] Syntax definition of `filter-functions` (#13309)

romainmenke has just created a new issue for https://github.com/w3c/csswg-drafts:

== [filter-effects-1] Syntax definition of `filter-functions` ==
https://github.com/w3c/csswg-drafts/blob/dd61a8cf2aff822edd584f4b54a8a0065bac802d/filter-effects-1/Overview.bs#L370-L371

https://github.com/w3c/csswg-drafts/commit/f6f0efa067f2b5c63ca764c00ebb8c316b513c44#diff-8be13fb6cc5f77ad353d66447f373758037137170db50c90abc48867e235a9e4R28-R371

This commit changed the definition to:
`blur( ) | brightness( ) | contrast( ) | drop-shadow( ) | grayscale( ) | hue-rotate( ) | invert( ) | opacity( ) | sepia( ) | saturate( )`

Effectively making arguments invalid for all of these.

Likely an intended change @tabatkins?
