use pip --break-system-packages instead of pipx ($PATH) instead of apt (old), #497

- 1.46GB`pipx install apprise` -> as is, need to adjust $PATH (now installed for root, note for #478)
- 1.45GB `pip install apprise --break-system-packages`
- 1.43GB `apt-get install apprise` -> only version 1.7.2 instead of 1.9.3 for pip/pipx

 # mega-linter (KICS, Trivy) complained about it missing - usually this checks some API endpoint, for a container that runs ~1min a healthcheck doesn't make that much sense since playwright has timeouts for everything.
