Marks the application as adaptive.
This change in the *.desktop file would make seahorse be displayed by default in the app tray of phosh on linux devices (Librem 5, Pinephone, postmarketOS with phosh running on android devices).
Currently phosh only displays by default in the app tray applications marked as adaptive, you need to select to show all apps for searhorse to be visible.
And the current version of seahorse is quite adaptive, it allows for people to manage the keyring passwords.
A merge request for this will follow in a bit.
