deskutils/gnome-shell-extension-simple-weather: Unbreak with gnome-shell 47

Tweak RUN_DEPENDS to fix:

===>   gnome-shell-extension-simple-weather-48.2.0 depends on package: gnome-shell>=48.0 - not found
*** Error code 1

Stop.
make: stopped making "run-depends" in /usr/ports/deskutils/gnome-shell-extension-simple-weather

when gnome shell is still version 47.x. The port does a patch that makes
it look like support goes back to 46.x.
