fix: RNTester TransformExample crash (facebook#35292)

Summary:
As pointed out by kelset on facebook#34660 (comment) accessing the `TransformExample` is currently crashing the `RNTester` app due to missing units in one of the transformers. This PR fixes it by updating the transform value to a valid string.

## Changelog

[Internal] [Fixed] - Add missing translate units to  `RNTester` `TransformExample`

Pull Request resolved: facebook#35292

Test Plan:
1. Open the RNTester app and navigate to the Transforms page
2. Check the transform style through the `Transform using a string` section
