Inline Reply where supported

[SolarLiner]

GNOME supports inline replies in notifications. This means having to avoid resorting to third-party solutions (like shell-calling zenity which could potentially be an attack vector to allow code execution).

The problem being, not all notification daemons support inline replies, and GNOME doesn't document well how to use them. This means having a fallback position.

In short:

• Find documentation on how to set notification as reply-able - most GJS projects that use it are old and deprecated (and there's something with GJS code that I can't really understand)

• Find a way to use documentation from the C++ library

• Think of a good fallback solution.
