Installation Documentation does not state risk on using "pm2 start umami" or how to make usage safe

[bbx-github]

Describe the Bug

In section Start the application installation documentation first states

By default this will launch the application on http://localhost:3000. You will need to either proxy requests from your web server or change the port to serve the application directly.

But in section Running Umami it is not stated that running umami as described lets it listen on http://*:3000.

The documentation should show how to make umami listen on http://127.0.0.1:3000 only using pm2 or at least warn that it does listen everywhere if it is setup as described.

We should probably move that PM2 content to a separate section.
