Subject: [PATCH] [playground] Report non-error-severity errors on compile
 failure

error.hasErrors() only returns true on error-severity errors. However,
non-error-severity errors (in this case, todos / hint severity)
caused invokeCompiler to throw an error. This caused
transformOutput to be returned as undefined, breaking the playground
and hiding the errors.

Fixes #34657
