remove maintenance number on older updater

Description

Updater was crashing when receiving maintenance number

We now send the current version number to the server that will adapt its answer and send maintenance number if updater has fixed the crash when receiving maintenance number, if the version number is sent it means the updater is new enough to support maintenance number
