- move all symbolic assets into their own subfolder in icon data
- drop assets that have a generic counterpart in Adwaita:
- desktop, phone, app-remove, content-loading
- rename assets to have semantic file names
- add new assets for action that were reusing other icons:
- drug-use, advertising, donations, contact, installed apps, touch support
- update symbolic assets with dated styles:
- explore, screen contents, translations, app safety, community, chat ratings
The call of the `upgrade` is not needed in the refresh-metadata job,
there's another dedicated job for this kind of work. To get what updates
are available the "automatic-update-trigger" with "check" mode is sufficient.
