Linkding is using postgresdb

[Kubernetes]

@girish very good job with changing the package to use postgresdb instead of sqlite. So the bookmarks are included in the cloudron backups.

I am really pleased myself to have linkding now offically on Cloudron

SQLite would have been backed up too if it was in /app/data

The issue with sqlite is, that it needs to know when to commit to disk to have consistent state for a backup. With the database addons, we have backup triggers.
