Client async functions return `unknow` ts type instead of the response types.

[Hyperkid123]

Example: https://stackblitz.com/edit/vitejs-vite-mygi8omd?file=src%2Fmain.ts

All client function return type are unknown instead of the AxiosPromise<T> type.

const rbacApi = APIFactory('/', {
  getPrincipalAccess,
});

// This is unknown but should be GetPrincipalAccessReturnType
const resp = rbacApi.getPrincipalAccess({
  application: 'foo',
  limit: 123,
});

The resp is of type unknown which means TS will not let you access the Promise API. You have to type cast the return value or ignore the TS.
