Add feedback while opening Wi-Fi settings from Tor Connection
Right now there is no feedback. We should have a spinner.
See:
* a previous attempt that broke things: https://gitlab.tails.boum.org/tails/tails/-/issues/18594#note_277474
* for some context about the current code: 2975b6f076bf5e3f2824b9f62632573766fc2cb2 and #18587
# To Do
* [ ] Verify that we get feedback
* [ ] Verify that the Wi-Fi settings appear when started from Tor Connection
* [ ] Verify that one can connect to a Wi-Fi network from the GNOME settings started from Tor Connection
