chore(utils): add type hints to utils functions [python]

[yogeshwaran-c]

Summary

Adds missing type hints to three functions in python/bullmq/utils.py:

• isRedisVersionLowerThan(current_version: str | None, minimum_version: str) -> bool
• extract_result(job_task: asyncio.Task, emit_callback: Callable[[str, Any], None]) -> Any
• get_parent_key(opts: dict[str, str]) -> Optional[str]

Also adds the necessary imports (asyncio, Callable, Optional).

Note: isRedisVersionLowerThan now treats current_version=None as "not lower" (returns False) instead of raising. This is a small but intentional runtime change: callers like RedisConnection.version are typed as str | None and previously would have crashed if checked before getRedisVersion() ran.

Motivation

These functions previously lacked type annotations, while the rest of the file (e.g. parse_json_string_values, object_to_flat_array, is_redis_cluster, get_cluster_nodes, get_node_client) is fully typed. This change brings consistency and improves IDE support / static analysis. Apart from the documented None-guard above, no other runtime behavior is altered.

Test plan

• No runtime behavior changes apart from the documented None-guard in isRedisVersionLowerThan
• Existing Python tests continue to pass

Pull request overview

This PR adds missing type annotations to a few helper functions in python/bullmq/utils.py to improve consistency and IDE/static-analysis support in the Python BullMQ implementation.

Changes:

• Added imports needed for typing (asyncio, Callable, Optional).
• Added return/parameter type hints for isRedisVersionLowerThan, extract_result, and get_parent_key.

Thanks for catching this! You're right that the current_version is None short-circuit is a small runtime behavior change, not purely an annotation change. I've updated the PR description to call this out explicitly.

The None-handling is intentional defensive behavior that matches the new current_version: str | None annotation: callers like RedisConnection.version start out as None until getRedisVersion() populates them, so returning False ("not lower than the minimum") is the safest default and avoids a TypeError from semver.Version.parse(None) if the check happens to run before the version is fetched. Treating an unknown version as "not lower" also matches the optimistic semantics the rest of the codebase assumes when version info isn't yet available.

Happy to split this into two commits (annotations-only + the None-guard) if you'd prefer that for review clarity.
