Description

Fixes #4589

openai_moderation expects input values are string but it can be a number when it has number type variable, and result in the following error:

ERROR:core.app.apps.chat.app_generator:Unknown Error when generating
Traceback (most recent call last):
  File "/Users/rerorero/go/src/github.com/rerorero/dify/api/core/app/apps/chat/app_generator.py", line 182, in _generate_worker
    runner.run(

    _, inputs, query = self.moderation_for_inputs(
  File "/Users/rerorero/go/src/github.com/rerorero/dify/api/core/app/apps/base_app_runner.py", line 356, in moderation_for_inputs
    return moderation_feature.check(
  File "/Users/rerorero/go/src/github.com/rerorero/dify/api/core/moderation/input_moderation.py", line 38, in check
    moderation_result = moderation_factory.moderation_for_inputs(inputs, query)
  File "/Users/rerorero/go/src/github.com/rerorero/dify/api/core/moderation/factory.py", line 37, in moderation_for_inputs
    return self.__extension_instance.moderation_for_inputs(inputs, query)
  File "/Users/rerorero/go/src/github.com/rerorero/dify/api/core/moderation/openai_moderation/openai_moderation.py", line 29, in moderation_for_inputs
    flagged = self._is_violated(inputs)
  File "/Users/rerorero/go/src/github.com/rerorero/dify/api/core/moderation/openai_moderation/openai_moderation.py", line 47, in _is_violated
    text = '\n'.join(inputs.values())

I confirmed this fix solved the issue.
