Add Python example for Bulk Granule Operations in API Docs

[HereIsMuhammad]

Feature Request

It would be very helpful if the Cumulus API documentation included a Python example for performing bulk granule operations (like inventory reports or batch processing).

Why

Currently, most examples are in JavaScript/Node.js, which may make it harder for Python developers to use the API. A Python example would make the documentation more inclusive and easier to understand for a wider audience.

Suggested Solution

Add a short Python script in the api-client-py section showing:

1. How to authenticate with the API.
2. How to fetch granule data.
3. How to generate a bulk inventory report.

This will help Python developers quickly integrate Cumulus API into their workflows.
