Adjust HelloWorld-tvOSTests/Info.plist CFBundleIdentifier to use PR ODUCT_BUNDLE_IDENTIFIER (#27601)

Summary:
In other part of the hello world, this replacement has been made already. The only place left this way (which make sense) is in `HelloWorld.xcodeproj/project.pbxproj`.

## Changelog

[General] [Fixed] - Adjust HelloWorld-tvOSTests/Info.plist `CFBundleIdentifier` to use PRODUCT_BUNDLE_IDENTIFIER
Pull Request resolved: #27601

Test Plan: I made this change locally on a project. No big deal as this is a test piece, not going to go on any kind of real world environment.
