[playground] Partially revert facebook#32009 (facebook#32035)

I had forgotten that our default error reporting threshold was `none`
due to the fact that build pipelines should not throw errors. This
resets it back to throwing on all errors which mostly is the same as the
eslint plugin.

Closes facebook#32014.
