Fix ruby unit tests (facebook#48498)

Summary:
As a prerequisite of enabling running unit tests on CI again, this PR suggests changes needed to the Ruby unit tests.

I've added comments on the code below, justifying changes where I deem a justification might be needed.

For use internally, I suggest accessing the folly_config and boost_config directly via the `Helpers` class instead of the `get_folly_config` and `get_boost_config` because these global functions are defined in `react_native_pods` which would be result in circular requires. An alternative would be to move these global functions to a separate file.

## Changelog:

[INTERNAL] [FIXED] - Fix Ruby unit tests.

Pull Request resolved: facebook#48498

Test Plan:
- `cd packages/react-native`
- `./scripts/run_ruby_tests.sh`
