Please use update-sgmlcatalog which is less generic than the other
name and is in line with the (supposedly fixed rename request for the
update-catalog command in an old edxperimental upload), see #88008. So
that we don't need to do the transition for the trigger later on too.

Otherwise the change looks good. I proposed using -noawait variants,
but given the current usage of the (implicitly) -wait ones, I'd also
leave this for now as an unrelated change that avoids possible breakage,
as you did here.

Thanks,
Guillem
