What happened?

/ventoy/ventoy.json is removed by Ventoy2Disk.sh -u /dev/sda

This is particularly bad, as the user is told that all the data is safe:

Upgrade operation is safe, all the data in the 1st partition (iso files and other) will be unchanged!

Demonstration:

% sudo mount /dev/sda2 /mnt/usbkey
% # Create an example ventoy.json to show that it will be removed later on:
% sudo touch /mnt/usbkey/ventoy/ventoy.json
% sudo umount /dev/sda2
% sudo /opt/ventoy/Ventoy2Disk.sh -u /dev/sda
