[1.x] Documentation issue (small) : addition about systemd needed

[Anth0ny6]

OS: Rocky Linux 9
Janus: build from latest sources

About problem.

Page: https://janus.conf.meetecho.com/docs/service.html
Stage: systemd

On Rocky Linux 9 (not tested on other RH-family operating systems), if the systemd unit "janus-gateway.service" does not contain a PIDFile= directive, the unit "janus-gateway.service" starts and stops immediately.

Thanks for the heads up! If you have text to propose for the documentation (as a PR or here) please feel free to contribute that, as I've never used Rocky Linux myself.
