Fix kubectl commands formatting in readme Example Output section

[Copilot]

Problem

The "Example Output" section in readme.md had kubectl commands listed as plain text without proper markdown code block formatting. This made them difficult to read and inconsistent with other command sections in the documentation.

Additionally, there was an incorrect command: minikube service kubectl describe svc plan-order-service which mixed two different commands together.

Solution

This PR fixes the formatting issues by:

1. Wrapping commands in a proper code block: Added ````sh` code block around the kubectl and minikube commands (lines 102-111) for better readability and consistency with the "Common Commands" section
2. Fixed command typo: Corrected minikube service kubectl describe svc plan-order-service to the proper syntax: minikube service plan-order-service

The commands now render properly in markdown viewers and users can easily copy and paste them.
