Update get_service_account_tokens.py

[mjeremia]

Improved comment to clarify what users should do when the access token expires. Access tokens are short lived; once they expire, a new token must be generated by rerunning this code. This improves clarity for beginners using the Firebase Admin SDK.

This pull request focuses on enhancing the user experience for those utilizing the Firebase Admin SDK by clarifying the instructions within a Python code snippet. The primary goal is to provide more explicit guidance on how to manage and regenerate access tokens, which are inherently short-lived, ensuring that users understand the necessary steps when a token expires. This change improves the readability and usability of the example code without altering its functional logic.

Highlights

• Comment Clarity: Improved the explanation within the get_service_account_tokens.py snippet regarding the short-lived nature of access tokens and the process for regenerating them once they expire. This provides clearer guidance for users, especially beginners.
