Type 'bigint' is not assignable to type 'Key | null | undefined' when trying to use virtualItem.key as react component key

Describe the bug

<SomeItem key={virtualItem.key} />

results in:

Type 'Key' is not assignable to type 'Key | null | undefined'.
  Type 'bigint' is not assignable to type 'Key | null | undefined'.ts(2322)

index.d.ts(98, 9): The expected type comes from property 'key' which is declared here on type 'IntrinsicAttributes'

I suspect this may be due to being on an older version of React than what the Key type is targeting? But I don't think this should matter.

const key = String(virtualItem.key); works fine as a workaround, but it'd be nice if either:

• Key type from installed version of React is used
• Key type is inferred from getItemKey
• Key type could be passed to useVirtualizer, like useVirtualizer<TItemKey>(...)

As always, great job with this library. I love it! ❤

Terms & Code of Conduct

• I agree to follow this project's Code of Conduct
• I understand that if my bug cannot be reliable reproduced in a debuggable environment, it will probably not be fixed and this issue may even be closed.

Start with the generated type declaration at index.d.ts line 98 and reproduce the error in main.tsx from the linked StackBlitz example. Compare the exposed virtualItem.key type with the React key type under TypeScript 4.9.5; done means key={virtualItem.key} type-checks without requiring the String workaround.
