Change backup directory to /opt for paperless-ngx (#9195)

* Change backup directory to /opt for paperless-ngx

Using /tmp for the backup is risky since many installations host it with tmpfs and thereby in RAM.

Having a bigger document base will deplete the memory on backup.

* Update paperless-ngx.sh

Added missing change.
