RNTester: compile RCTUtilsTests in the RNTesterUnitTests target (#58894)

Summary:
`packages/rn-tester/RNTesterUnitTests/RCTUtilsTests.m` isn't in `RNTesterPods.xcodeproj`. It's the one test file in `RNTesterUnitTests/` with no file reference and no Sources entry, so `yarn test-ios` never compiles it and `testRCTHumanReadableType` and `testRCTValidateTypeOfViewCommandArgument` never run. This adds the file to the `RNTesterUnitTests` target.

## Changelog:

[INTERNAL] [FIXED] - Compile RCTUtilsTests in the RNTesterUnitTests target

Pull Request resolved: #58894

Test Plan:
- `xcodebuild test -workspace RNTesterPods.xcworkspace -scheme RNTester -sdk iphonesimulator -destination 'platform=iOS Simulator,id=<udid>' -only-testing:RNTesterUnitTests/RCTUtilsTests`: on `main` it executes no tests; with this change it executes 2, and both pass. Changing the expected value of the first assertion makes the run fail.
- The whole `RNTester` scheme, with Metro and the WebSocket test server up as `scripts/objc-test.sh test` starts them: `RNTesterUnitTests` 170 tests, 16 skipped, 0 failures, with both `RCTUtilsTests` cases among them. I ran it on the iOS 18.0 runtime; `scripts/.tests.env` asks for 18.3.1, which this machine doesn't have.
