[HEAP-45444] Resolved critical warnings and got unit tests working

[bnickel]

HEAP-45444

The primary change in this PR is the removal of the @expo/config-plugins@^4.1.5 dependency. This dependency wasn't needed because Expo already imports @expo/config-plugins as one of its dependencies and if you aren't using Expo you don't need to bring in the stack. It's not even worth calling for a peer dependency in this case.

While working through that, I decided to clear up any critical warnings and build issues in the SDK so we can run the following commands without issue:

• npm install
• npm run test
• npm run test-instrumentor

That resulted in the following changes:

• Adding yarn classic to the repo so expo-module prepare doesn't fail.
• Updating all the devDependencies to their latest major version.
• Updating any minor dependencies that had critical issues.
• Updating the instrumentor test fixtures to the latest babel output.
• Switching the unit tests from ember to @testing-library/react-native and updating the fiber lookup code to reflect that change.
• Adding a script to sync the version from package.json to a source file on compile/prepare so we don't keep running into json compile errors.

Test Plan

• Unit tests were run.
• The expo plugin was added to a project that was then exported. strings.xml had the expected changes.
• Expo tests have not been run yet due to issues with my new machine but there's no functionality changing.
• Compared diffs of npm pack and the current release to confirm nothing's really changing.

Checklist

• [ ] Detox tests pass
• [x] If this is a bugfix/feature, the changelog has been updated
