Firebase logger structured logs for v2 Cloud functions are missing labels.

[REQUIRED] Version info

**node:**16 **firebase-functions:**3.24.1 **firebase-tools:**11.19.0 **firebase-admin:**11.3.0

[REQUIRED] Test case

Create a log from a v2 Cloud Function. Invoke the function. Go to Firebase console > Functions. Click on 'View logs' for previously created function. Logs will be empty because labels are missing.

[REQUIRED] Steps to reproduce

Create a v2 Cloud Function and, using logger, create a structured log, for example:

      functions.logger.debug('Hello world', { structuredData: true });

Inspect the output in your logs.

[REQUIRED] Expected behavior

v2 function logs are similar to v1 function logs, which include labels: function name and version, like this example v1 log label:

[REQUIRED] Actual behavior

v2 function does not include any labels.
