Remove: Booklore

[MickLesk]

✍️ Description

This PR removes Booklore from Proxmox Helper Scripts.

The original project has been discontinued and is no longer maintained.

While a community fork (Grimmory) exists, we have decided not to provide an official migration or support at this time due to:

• lack of a stable, clearly defined migration path
• ongoing structural changes in the project
• no reliable upstream collaboration or support for this use case

The @community-scripts/contributor team and Helpers agreed to prioritize long-term stability and avoid introducing solutions that may require rework in the near future.

Users who wish to continue can evaluate Grimmory independently (e.g. via Docker), at their own responsibility. Backups are strongly recommended.
