bug#48142: [PATCH v2] gnu: gupnp: Add missing input.

[Jack Hill]

Fixes <https://bugs.gnu.org/48142>.
Reported by Shyam Saran <syamsaran12345@gmail.com>.

This fixes the fatal error "Settings schema 'org.gnome.system.proxy' is not
installed", which causes builds to fail.

* gnu/packages/gnome.scm (gupnp)[inputs]: Add gsettings-desktop-schemas.
