Walkthrough

getLanguageCode() was updated to compare stored language codes and the requested language case-insensitively. A new test covers a region-tagged canonical code, de-DE, and checks that the function returns the canonical casing when matched.

In `@packages/react-native/src/lib/common/tests/utils.test.ts`:
- Around line 457-465: The test in getLanguageCode is not proving
case-insensitive matching because it uses the same casing for input and expected
output. Update the region-tagged canonical code case in the utils.test.ts suite
so getLanguageCode is called with a differently cased value like "de-de" while
still expecting the canonical result "de-DE", keeping the existing survey
fixture and assertion structure intact.
