[Pkg-sugar-devel] Bug#1079428: sugar-pippy-activity: please migrate from deprecated gtksourceview3 to gtksourceview4 (or 5)

gtksourceview3 was superseded in 2018 by gtksourceview4 (a new major
upstream release, but still using GTK 3). There's a porting guide here,
which is mostly "stop using deprecated APIs" plus a few function renames:
https://gnome.pages.gitlab.gnome.org/gtksourceview/gtksourceview5/porting-guide-3-to-4.html

That porting guide is for C code, but the function renames required to move
from gir1.2-gtksource-3.0 to gir1.2-gtksource-4.0 are probably very similar.

gtksourceview3 is unmaintained and hasn't had an upstream release for more
than 5 years, so it would be great if the remaining gtksourceview3
applications can move to gtksourceview4 before trixie.

gtksourceview4 has itself been superseded by gtksourceview5, which is
for GTK 4 applications. Ideally GTK 3 applications should move to GTK 4,
but that's a larger and more intrusive change. Porting guide:
