fix: Add missing tvOS steps to build-hermes-macos GH action (#47073)

Summary:
After examining Hermes artifacts built after merging of https://github.com/facebook/react-native/issues/46865 , it was apparent that tvOS frameworks were missing from the Hermes universal framework generated by CI.

I went back and discovered additional steps that need to be added to the `build-hermes-macos` action to make CI work correctly.

## Changelog:

[Internal][Fixed] add required steps to build tvOS in build-hermes-macos action

Pull Request resolved: https://github.com/facebook/react-native/pull/47073

Test Plan: After merging, Hermes artifacts generated by CI should contain the missing tvOS bits.
