feat(nova/react-test-utils): make types for referenceEntries stronger

[sjwilczynski]

We previously did some work to add good, strong types for parameters for nova decorator. One of the big things was making sure that referenceEntries fields match props of the component. However, we are now verifying only if the name of the prop matches, instead of of actually checking the value, which causes a number of random errors for folks using this in 1JS.

In scope of this PR we add a validation of return type of each field in referenceEntries. So previously

referenceEntries: {
       // the key "feedback" is checked against component props but the return value of the function is ignored
        feedback: (data) => data.feedback,
},

now

referenceEntries: {
       // also "data.feedback" is checked so that it matches the type that feedback prompt on the component expects
        feedback: (data) => data.feedback,
},

Thanks to @MikeBarker-MSFT for providing a first version of this within 1JS

This looks like a REALLY good addition to the testing framework. Thank you for adding.

Minor nit, this should already be available with (iirc) React.ComponentProps<T>
