🐛 Fix optional sequence handling with new union syntax from Python 3.10

https://github.com/fastapi/fastapi/pull/14297 is only taking one union type into account. I can only recommend using https://github.com/pydantic/typing-inspection for these kind of checks (see https://typing-inspection.pydantic.dev/latest/usage/ for motivation).
