Switch to libsoup3
GNOME Core has switched to libsoup3 for the 43 release.
chatty needs to switch to libsoup3 since its dependency evolution-data-server has switched (at least as built as part of core GNOME 43). It's not possible for an app to link against both libsoup2 and libsoup3 simultaneously.
If you need to enable the latest version of chatty to run on older distros, you might need a build option to switch between libsoup2 and libsoup3.
