Make `useDispatchedActionData` default to `true` in the next major version

The `ReactNavigationIntegration` has a `useDispatchedActionData` option (currently defaulting to `false`) that uses dispatched action data to improve navigation span quality:

* Names spans immediately from the action payload instead of starting with a generic "Route Change" name
* Skips spans for actions without a known route name (GO_BACK, POP, POP_TO_TOP, RESET), reducing noise
* Filters out non-navigation actions (SET_PARAMS, OPEN_DRAWER, CLOSE_DRAWER, TOGGLE_DRAWER)

This option was introduced as opt-in to avoid breaking changes, but it provides a strictly better experience for all users. In the next major version (9.x), we should flip the default to true.

定位 ReactNavigationIntegration 的定义和 useDispatchedActionData 选项，然后检查其默认值是如何为即将推出的 9.x 主版本声明的。将默认值改为 true，并验证文档所述的 action 名称、跳过的 span 和过滤行为仍由现有的集成测试覆盖（如果存在这些测试）。
