[Autocomplete] extend renderOption prop type to allow key and ref

[PascalLuginbuehl]

• I have followed (at least) the PR section of the contributing guide.

I would like to be able to override the key property for renderOption. Like so

renderOption={(props, option, state) => renderOption({ ...props, key: option[optionValueField] }, option, state)}

Unfortunatyle this throws the following error
Object literal may only specify known properties, and 'key' does not exist in type 'HTMLAttributes<HTMLLIElement>'.

This merge request fails because React.DetailedHTMLProps still uses LegacyRef which enables the ref to be a string.

OverridableComponent no longer supports LegacyRef, only the new Ref type, Thats why the following error occurs

Type 'LegacyRef<HTMLLIElement> | undefined' is not assignable to type 'Ref<unknown> | undefined'.
          Type 'string' is not assignable to type 'Ref<unknown> | undefined'.

I would appreciate some help on this matter.

@PascalLuginbuehl please open an issue and we can take a look and provide fix there. Looks like the renderOption you are talking about is defined in your codebase. When creating an issue make sure to share codesandbox with the whole code, so that it's clear what's the problem.
