Hello,

Emacs with xwidgets support needs webkit2gtk-4.0, which for us means the variant built with libsoup2 on core-updates-frozen. I've changed the inputs in the two affected Emacs packages and added to the comment about where webkitgtk-with-libsoup2 is used. Apologies if the formatting/style of the commit message is off, wasn't sure how best to do this.

John
