补充 TooltipProps 中的弹出层属性类型。

当前 TooltipProps 未声明 popupClassName 和 popupStyle。因此这段 JSX 会触发 TypeScript 的“属性不存在”错误，TypeScript 使用者也无法类型安全地使用本次新增的合并行为。

请将这两个字段加入 TooltipProps，例如加入 Pick<TriggerProps, 'popupClassName' | 'popupStyle'>。

在 TooltipProps 中加入从 TriggerProps 选取的 popupClassName 和 popupStyle
属性类型，使这两个弹出层属性可在 Tooltip JSX 中通过 TypeScript 类型检查，并保留现有属性合并行为。
