Nested Docs plugin callback signatures do not match current type hints

[ItsFrankieD]

Documentation Issue

The current documentation for Nested Docs shows generateLabel: (_, doc) and generateURL: (docs), while the type hint in the current version at the time of writing (3.44.0) shows generateLabel: (docs: Array<Record<string, unknown>>, currentDoc: Record<string, unknown>) and generateURL: (docs: Array<Record<string, unknown>>, currentDoc: Record<string, unknown>).

When I attempt to return something like currentDoc.title, I am given a TypeScript error as it assume I am returning unknown as opposed to a string.

The documentation needs to be updated, as in its current state it's unusable.
