Gnumeric doc strings not extracted by D-L
Docs for Gnumeric now only contain 84 strings according to https://l10n.gnome.org/module/gnumeric/
For some reason only strings in gnumeric.xml are extracted. Looking at https://gitlab.gnome.org/GNOME/gnumeric/-/blob/master/doc/Makefile.am, there are many more xml files marked HELP_EXTRA
that should have strings extracted as well.
This extraction has worked previously, and I didn't see any obvious cause in recent gnumeric changes. Did something change on l10n.gnome.org?
