[Autocomplete] Typization mistake in AutocompleteRenderGroupParams

[khrulenko]

Steps to reproduce

Steps:

1. Reach params in renderGroup in Autocomplete
2. Check the actual type of key (it's number)
3. Compare the type of key with the type in AutocompleteRenderGroupParams (it's string)

Current behavior

export interface AutocompleteRenderGroupParams {
key: string;
group: string;
children?: React.ReactNode;
}

Expected behavior

export interface AutocompleteRenderGroupParams {
key: number; ←←←
group: string;
children?: React.ReactNode;
}

Upon checking renderGroup in Autocomplete component, the key prop is of type string, also has an implicit conversion to string to be safe.

Actual type of params.key is number despite of Typescript shows that the type is string.
params.key should be a string. Or type should be changed to number.
