#52836 breaks fragmented-store on DT

#52836 broke fragmented-store on Definitely Typed. Here's a repro that doesn't depend on React:

type StateHook<S> = () => [S, unknown];

type StoreUtils<Store extends { [K: string]: any }> = Omit<{
    [K in keyof Store as `use${Capitalize<string & K>}`]: StateHook<Store[K]>
}, 'useStore'> & {
  Provider: unknown,
  useStore: StateHook<Store>
};

declare function createStore<Store extends { [K: string]: any }>(store: Store): StoreUtils<Store>;

const { Provider, useUsername, useAge, useStore } = createStore({
  username: "Aral",
  age: 31
});

I have literally never heard this term ever

Sorry, it's the name of a package on Definitely Typed. Edited the OP for clarity.
