chore: fix React SDK README.md to use the resolved value instead of t…

…he resolution details (#691)

## This PR

The documentation conditionally renders something if the returned value
from the hook is truthy, but this implies that it is simply checking for
the entirety of the `EvaluationDetails<T>` returned from
`useFeatureFlag` which seems off since we will always get an object back
according to the typings. It feel like it should be checking against the
`.value` to conditionally render the elements.
