Detect optional parameters that have "pass null" in their description

[nikstar]

Detect parameters that have "pass null" in their description similar to how "may be null" is detected. These are now correctly marked as optional.

For example, here:

/// Options to be used when a message is sent
public struct MessageSendOptions: Codable, Equatable, Hashable {

    ...

    /// Message scheduling state; pass null to send message immediately. Messages sent to a secret chat, live location messages and self-destructing messages can't be scheduled
    public let schedulingState: MessageSchedulingState? 👈

    ...
}

Hi @nikstar, thank you for the contribution. It's indeed useful not to pass useless nulls.

Such pain can only be found if you're working a lot on something TDLib-based. Perhaps you can share what you're working on...?

To be clear, I just wanted to configure some send options but pass null for scheduling state, which wasn't possible because schedulingState was non-optional.

Perhaps you can share what you're working on...?

Not yet, sorry :)
