Tests: Use assertSame() in `WP_REST_Global_Styles_Revisions_Control…

…ler` tests.

This ensures that not only the return values match the expected results, but also that their type is the same.

Going forward, stricter type checking by using `assertSame()` should generally be preferred to `assertEquals()` where appropriate, to make the tests more reliable.

Follow-up to [56082].

See #61573.
