[Bug]: In Github CodeSpace, Storybook dev mode return response without content type as raw string

[64BitAsura]

Describe the bug

Within a GitHub CodeSpace environment, you are running Storybook in development mode. However, you notice that the responses generated in this mode are lacking a content type specification entirely, causing them to be interpreted as raw strings. This absence of a defined content type may lead to challenges in how the responses are handled or processed by other components of your application.
