Debounce missing in TypeScript and docs

[dricholm]

Description

I see the debounce functionality was added recently in #2760, thank you for that!
Already managed to use it successfully, but noticed that the types haven't been updated to support it so had to use @ts-expect-error to avoid TypeScript errors.
Also there is no mention of it in the docs yet, mainly looked up the functionality in the above PR and in the BullMQ docs.

Could the types be updated to support debounce? I assume it would mean adding debounce?: { id: string; ttl?: number } to JobOptions and removeDebounceKey(debounceKey: string): Promise<number> to Queue. If that's all it would be I could also help in contributing.
Additionally would be good to also mention this useful function in the docs somewhere. Would it only need changes in REFERENCE.md?

Bull version

4.16.0
