APT repo recreated (on update / open)
I'm not sure exactly when this happened, but when updating 1Password through apt, i received messages informing me that the target is configured multiple times.
this occurred because I swapped all external apt repos to use the new deb822 style format, excluding some explicitly automatically managed files
the 1password file was not marked as automatically managed, so it was converted to the new style and removed, but came back.
(i think it was probably on update, but i don't know exactly)
compared to the google chrome file, which i explicitly knew to not touch due to the comment, identical to the other electron based apps
(slack, vscode)
