Fails to update Plesk docker extension

[dennisameling]

Describe the bug
I ran the upgrade script and it failed at the Update Plesk extensions phase, specifically on the Docker extension:

I then ran /usr/sbin/plesk bin extension -i docker manually on the command line, which finished successfully. After that I ran ./debian11to12 --resume to resume the process where it left off. This time, it was able to finish the upgrade.

So I was able to complete the upgrade, but wanted to make you aware of this potential bug/issue in the upgrade script.
