[BUG] Don't drop stack traces

[iirekm]

Describe the bug

In pyflyte run ... I'm getting:

Encountered error while executing workflow ...:
  Error encountered while executing 'train':
  isinstance() arg 2 must be a type, a tuple of types, or a union

Dropping stack traces from console logs is an anti-pattern, making debugging very hard.

Ugly workaround (possible only on local machine): to WorkflowBase.__call__'s except block add:

            import traceback
            print(traceback.format_exc())

Flytekit version: 1.9.0

Expected behavior

Full stack trace should be preserved.
