### $upgrade_type can have 2 different values

### - UPGRADE_APP if the upstream app version has changed
|
|
### - UPGRADE_PACKAGE if only the YunoHost package has changed
|

### ynh_check_app_version_changed will stop the upgrade if the app is up to date.
|
|
### UPGRADE_APP should be used to upgrade the core app only if there's an upgrade to do.
