Unable to Clear Query Parameters

[RyoSogawa]

Describe the bug

Thank you for the awesome addon.
It seems like I can no longer clear query parameters as I could in previous versions.

The ability to clear query parameters is crucial for resetting parameters specified in another story.
Could you please look into this issue? Thank you!

Steps to reproduce the behavior

// stories.tsx
export meta = {
  parameters: {
    query: {
      id: undefined,
      name: null,
    },
  },
};

in the current version, it generates query parameters like:

?id=undefined&name=null

Expected behavior

In version 6.x, the above code wouldn't set the query parameters.

Environment

• OS: MacOS
• Node.js version: v18.x
