Update suggested command for busy port detection during the start

[juazugas]

Change the suggested command for busy port detection with the utility to dump socket statistics.

The command netstat was deprecated in linux and it is being retired from the default installed networking tools. The suggested command to look for the busy port may not be installed by default on the latest linux distributions (as it happened to me).

Find more information on the new tools on the article :
https://www.redhat.com/sysadmin/deprecated-linux-command-replacements

or the replacement announcement :

Thanks for taking the time to open a PR.
I think we should keep the reference to netstat though as macOS doesn't have ss (and I'm not sure the BSD have it).

Can you adjust and squash? Thanks!

I force pushed a small update to fix the formatting issue.
