fix misleading localhost comment for proxy_1 service URL

[erenyegit]

What changed

• Fixed an incorrect comment that labeled proxy_1 as localhost in the CLI getting-started guide.
• Updated the example to use the correct Docker network service URL.

Why this matters

• proxy_1 is a Docker service hostname and is not reachable via localhost.
• The previous example caused copy/paste failures for users running commands outside the Docker network.
• This change prevents confusion and aligns the documentation with actual Docker networking behavior.

Scope

• Documentation-only change (no code or behavior changes).

Summary by CodeRabbit

• Documentation
  • Updated CLI getting started guide with corrected example URLs for docker network environments, clarifying configuration for publish and subscribe operations.

Poem

🐰 A docker hop, a port we've changed,
From 8081 to 8080 arranged,
No localhost, but network true,
The guide now shines in proxy's hue! 🌐
