fix: update id parameter name in celery-v2 headers

#7982, #422

Description (What does it do?)

This PR fixes an incorrect parameter name in the extract_proto2_headers function that I introduced in my previous PR. I mistakenly used task_id as a parameter when the actual Celery protocol v2 specification uses id for the task identifier in headers (as documented in the official Celery protocol docs). This was causing TypeError: extract_proto2_headers() missing 1 required positional argument: 'task_id' in production.

The fix removes the incorrect task_id parameter and uses the correct id parameter as specified by Celery's protocol v2.
