fix: respect to the "testingLibrary" config option

[yusufyildirim]

Summary

I found out that the testingLibrary option provided in the config object is not respected in the getTestingLibrary function. The function returns 'react-native' no matter what we provide in the configuration.

Looks like the early return statement accidentally removed or forgotten during the v1 effort.

measureRenderInternals function relies on getTestingLibrary and runs this code for react-native. It throws an error with react testing library, thus this tiny mistake makes reassure unusable with react testing library. This PR addresses that issue.

Test plan

Provide react as testingLibrary config option
Ideally, see if it works with @testing-library/react (I don't think there's a setup for that in the repo)
Or, check if getTestingLibrary and resolveTestingLibrary functions resolve properly.
