Remove pytest_benchmark_update_json hook to fix plugin validation error

The hook was causing 'unknown hook' errors when pytest-benchmark wasn't installed.
Removed the hook entirely since pytest-benchmark is not a dependency in the workflow.
Users can add pytest-benchmark if they need benchmark display functionality.
