Return type of the `CreateMethod` is not correct

[kostysh]

Here is the type of the CreateMethod:

export type CreateMethod = <T extends JobAttributesData>(name: string, data: T) => Job; // `Job` is not properly typed

Job itself has the following type:

declare class Job<T extends JobAttributesData = JobAttributesData> { /* ... */ }

This way a return type of the CreateMethod has to look like this:

export type CreateMethod = <T extends JobAttributesData>(name: string, data: T) => Job<T>;

@code-xhyun maybe it will be more helpful if I will create PRs from time to time? Not too often )
