Difference from teknologist's version:

• Base image switched to python:3.13-alpine3.23 to reduce image size (≈900 MB → ≈80 MB).
• added actions to build image and publish to docker hub.
• added a health check
• added a persistent /config volume for configuration.

Nut2 has a deprecated dependency on telnetlib; change the dependency to nut2-notl when building.

telnetlib — Telnet client
Deprecated since version 3.11, removed in version 3.13.
