fix: add init: false to config.yaml to fix s6-overlay v3 startup crash

s6-overlay v3 (used in HA base images) requires running as PID 1.
Docker's default --init flag prevented this, causing:
  's6-overlay-suexec: fatal: can only run as pid 1'

Setting init: false in config.yaml disables Docker's default init
so s6 correctly runs as PID 1. Dockerfile reverted to simple CMD.

Ref: https://developers.home-assistant.io/blog/2022/05/12/s6-overlay-base-images/
Bump version to 0.2.3.
