Remove redundant __DEV__ condition (#32810)

It used to be that in `__DEV__` we wrapped this `renderWithHooks`,
`checkDidRenderIdHook` pair in calls to `setIsRendering()`. However,
that dev-only bookkeeping was removed in
https://github.com/facebook/react/pull/29206 leaving this redundant
check which runs identical code in dev and in prod.

## Test Plan

* Manually confirm both cases are the same
* GitHub CI tests
