useDebouncedCallback doesn't consider its dependencies

[fabn]

Describe the bug

This is the same issue reported in #386 for useDebouncedCallback, I don't know why that issue has been closed. I'd expect that any dependency given as args will invalidate the callback but that's not the case because deps are not given to the useEffect call here. As result the callback sees the values as one step behind.

To Reproduce

Here's a codesandbox to reproduce the issue https://codesandbox.io/p/sandbox/pedantic-grass-f9f6qw

Expected behavior

When I click on useDebouncedCallback button I should see same values as other buttons in console, but I see the old counter value.

Hey @fabn thanks for opening this issue, I really appreciate it
Yeah this is definitely a bug and should be a one-liner, please feel free to open a PR yourself if you feel like it

I tried various changes including this one but it seems to not fix the problem.

const useDebouncedCallback = <TCallback extends GenericFunction>
  (fn: TCallback, dependencies?: DependencyList, wait: number = 600, options: DebounceOptions = defaultOptions) => {
  const debounced = useRef(debounce<TCallback>(fn, wait, options))
  const actualDependencies = dependencies ?? []

  useEffect(() => {
    debounced.current = debounce(fn, wait, options)
  }, [fn, wait, options, ...actualDependencies])

  useWillUnmount(() => {
    debounced.current?.cancel()
  })

  return useCallback(debounced.current, actualDependencies)
}

Hi @fabn, probably too late, but I submitted a PR that fixes the problem.
