refactor(batch): improve type annotation for event parameter (#7924)

fix(batch): improve type annotation for event parameter

Change event parameter type from 'dict' to 'dict[str, Any]' in
process_partial_response and async_process_partial_response functions.

Lambda events are JSON objects which should be typed as dict[str, Any]
for better type checking with tools like pyright.

Fixes #7923
