Further clarify link picker test intent

The assertions of these tests do not tell the full story of the test
expectation. Namely, due to bugs within react-native-testing-library and
its dependencies, the tests do not assert navigation events that should
occur _after_ the keyboard dismisses. Combining async renders and mocked
timers is currently quite difficult.

callstack/react-native-testing-library#379 (comment)

To clarify the intent of the test, the test description was expanded to
describe the expectation that the keyboard is dismissed prior to the
navigation event occurring. Simultaneously dismissing the keyboard and
navigating has caused performance issues in our bottom sheet before.
