Fix 'value' does not exist on type 'HTMLElement'

It’s common to see the error Property 'value' does not exist on type 'HTMLElement' when working with react testing library.

Common advice online is to cast result using the as operator.

const title = getByPlaceholderText("test") as HTMLInputElement;

This is fine but feels incorrect and when using eslint-typescript will complain that the cast is unnecessary: This assertion is unnecessary since it does not change the type of the expression.

Then, thanks to this SO answer, I learned that the react testing library query methods can now take an optional type parameter:

    screen.getByLabelText<HTMLInputElement>("test").value,

This feels much cleaner and makes both the linter and compiler happy.
