use non deprecated way to get record name

multiple locations [1] get record name using `._name` which is marked as deprecated [2]

we could have an utility function that uses the modern way and falls back to `_name` if not found to be backward compatible but allow future versions of immutable to drop `._name`.

从 packages/devtools/src/createFormatters.ts 中访问 `._name` 的两个引用位置开始，然后将 Record.js 中已弃用的 API 参考与现代的 record-name API 进行比较。集中处理查找并保持向后兼容，同时验证 record 格式化仍能获取名称，而不直接依赖已弃用的访问方式。
