Enables react/no-unstable-nested-components

This rule is likely either going to be in the recommended preset or move to rules-of-hooks. Wanted to see how this rule performs on a medium size repo and the errors all look legitimate to me (although it's all just test-code).

The idea here is that PolymorphicComponentTest looks like a component (and therefore would allow a hooks call). But inside of it we're declaring new components which is bad. Since it's not actually a component, we adjust the name to reflect that.

const polymorphicComponentTest = () => {
const CustomComponent: React.FC<{ stringProp: string; numberProp: number }> = () => <div />;

Suggested change
const polymorphicComponentTest = () => {
const CustomComponent: React.FC<{ stringProp: string; numberProp: number }> = () => <div />;
const CustomComponent: React.FC<{ stringProp: string; numberProp: number }> = () => <div />;
const PolymorphicComponentTest = () => {

Would this be better? I know that it produces no difference here since we are not using polymorphicComponentTest but it seems like a component here (or polymorphicComponentTest is not needed at all).

I usually keep things specific to a test in its scope before hoisting up. That way other tests don't start to rely on it. Up to you, what you prefer.

That sounds good to me as well.

I guess we could also disable react/no-unstable-nested-components for the TypeScript tests.

It's still "invalid React". Better to write it correct everywhere.
