Python 3.10+ type hint syntax incompatible with Python 3.9 (Odoo 16.0)

• Line 30: def _acquire_job(cls, env: api.Environment, job_uuid: str) -> Job | None:

Details

The union operator (|) for type hints was introduced in PEP 604 for Python 3.10. For Python 3.9 compatibility, this should use the Optional type from the typing module or the older Union syntax.
