Describe the issue

I am using this client in my Terraform provider and currently face an error when the Kinde API returns a JSON property with a null value.

E.g. if I create a permission without description, I am not able anymore to fetch it with this client as the decoding fails:

Create request code:

_, err := HandleResponse[SuccessResponse](r.client.CreatePermission(ctx, NewOptCreatePermissionReq(CreatePermissionReq{
	Name:        ToOptString(data.Name),
	Key:         ToOptString(data.Key),
	Description: ToOptString(data.Description),
})))

Example request body:
{"name":"CMI Show Dashboard","key":"cmi:show:dashboard"}

Read request code:

response, err := HandleResponse[GetPermissionsResponse](r.client.GetPermissions(ctx, GetPermissionsParams{
	Sort:      NewOptNilGetPermissionsSort(GetPermissionsSortIDDesc),
	PageSize:  NewOptNilInt(10),
	NextToken: currentToken,
}))

Example response body:

{
    "code": "OK",
    "message": "Success",
    "next_token": "MTo6OmlkX2Rlc2M=",
    "permissions": [
        {
            "id": "019a12ad-0dad-117d-a831-083bf2fdab86",
            "key": "cmi:show:dashboard",
            "name": "CMI Show Dashboard",
            "description": null
        }
    ]
}

Error while parsing:

decode response: decode application/json: decode GetPermissionsResponse: callback: decode field \"permissions\": callback: decode Permissions: callback: decode field \"description\": unexpected byte 110 'n' at 208"

I run into the same issue with NextToken when fetching all permissions (GetPermissionsResponse).
