[Bug] types of properties in group are inferred as unknown if results parameter is used

[brc-dd]

Environment

• OS: webcontainers
• Node Version: 18.20.3
• Package: @clack/prompts
• Package Version: v0.10.0

Describe the bug

const options = await p.group(
  {
    injectNpmScripts: async () => {
      return p.confirm({
        message: 'Add VitePress npm scripts to package.json?',
      });
    },

    addNpmScriptsPrefix: async ({ results }) => {
      if (!results.injectNpmScripts) return false;

      return p.confirm({
        message: 'Add a prefix for VitePress npm scripts?',
      });
    },
  },

  {
    onCancel: () => {
      p.cancel('Cancelled.');
      process.exit(0);
    },
  }
);

options here is inferred as:

const options: {
    injectNpmScripts: boolean;
    addNpmScriptsPrefix: unknown;
}

To Reproduce
https://stackblitz.com/edit/node-1z7qkqdt?file=index.ts

Expected behavior
Return correct types:

const options: {
    injectNpmScripts: boolean;
    addNpmScriptsPrefix: boolean;
}

Additional Information
It works fine if we make it ({ results }: any). The generic parameter of group function doesn't work because the functions return cancel symbol too.
