Use "*-new-*" feedback also when phone is locked

Currently we only use the *-missed-* feedbacks when the shell is locked and we get a notification. We should rather use the *-new-* feedback and then afterwards send the *-missed-* feedback in

https://gitlab.gnome.org/World/Phosh/phosh/-/blob/main/src/notifications/notify-feedback.c#L56

as the user doesn't get audible feedback otherwise. That is the shell side fix of https://source.puri.sm/Librem5/feedbackd/-/merge_requests/69 which gives us more control rather than munging things on the feedbackd side.

Reasoning is that if we get a notification we should alert accordingly. If the user wants silent (just led) he/she will have that configured anyway so using the *-new-* feedbacks will not create additional noise.

When fixing this we should fix https://source.puri.sm/Librem5/chatty/-/issues/657 to not have double feedback which looks like workaround for the current state in phosh.

With this applications can just send a notification with the appropriate category and don't need to care further.
