Incorrect types on RedirectHandler

[koterpillar]

Bug Description

The type for RedirectHandler constructor says the dispatch parameter takes a Dispatcher class, but the JS code uses dispatch as a function (that satisfies Dispatcher.dispatch).

Reproducible By

The example is compiled from the documentation:

undici/docs/docs/api/Dispatcher.md

Lines 871 to 876 in 242ec9b

	const redirectHandler = new RedirectHandler(
	dispatch,
	maxRedirections,
	opts,
	handler
	)

and the implementation of compose:

undici/lib/dispatcher/dispatcher.js

Line 23 in 67f3c96

let dispatch = this.dispatch.bind(this)

const client = new Client('', {})
const handler: DispatchHandler = {}

// ERROR: Argument of type (options: DispatchOptions, handler: DispatchHandler) => boolean is not assignable to parameter of type Dispatcher.
const redirectHandler = new RedirectHandler(client.dispatch.bind(client), 10, {
  path: '/', method: 'GET'
}, handler, false)

Expected Behavior

The parameter type is the same as Dispatcher.dispatch, and the example compiles successfully.

Environment

macOS 15.4.1, NodeJS 23.11.0

Additional context

The implementation of RedirectHandler constructor was updated in #1338, but the types weren't.
