Backport v2023 <- v2024pre: Relax hmi-switch-graphical-applications to use any application

Backport !567 (merged)

The test hmi-switch-graphical-applications requests to open Fonts application which is installed by default in HMI images via Flatpak, but not installed on SDK. Since the test can be run with any graphical application, relax it and mention Fonts only as a suggestion.
