[csswg-drafts] [css-grid-2] Clarify auto margins on subgrids (#13206)

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

== [css-grid-2] Clarify auto margins on subgrids ==
https://www.w3.org/TR/css-grid-2/#subgrid-box-alignment

> The subgrid is always stretched in its subgridded dimension(s): the align-self/justify-self properties on it are ignored, as are any specified width/height constraints.

We should clarify that auto margins resolve to zero.
