[No QA] Revert "Update CODEOWNERS so that we don't accidentally deploy a new version of react-native-onyx"

[tgolen]

Reverts #13952

We are rolling out the SQLite upgrade today, so it's no longer necessary for me to review these PRs.

No testing or checklists required since this change doesn't affect the App code

@puneetlath looks like this was merged without a test passing. Please add a note explaining why this was done and remove the Emergency label if this is not an emergency.

✋ This PR was not deployed to staging yet because QA is ongoing. It will be automatically deployed to staging after the next production release.

This is a simple revert that doesn't affect product-facing code, so the checklist didn't make sense in this scenario.
