[Fizz] Align recoverable error serialization in dev mode (#28340)

Same as #28327 but for Fizz. One thing that's weird about this recoverable error is that we don't send the regular stack for it, just the component stack it seems. This is missing some potential information and if we move toward integrated since stacks it would be one thing.
