Resolution Note:
This behaviour is by-design. It's not currently possible to call job.Schedule(...) if at the call site the job type has generic type arguments that have not been substituted with concrete types. In the call to job.Schedule(...), SpawnerJob has a generic type argument TSpawnerComponentType, which Burst is unable to resolve to a concrete type.
