[Typo]: change info about startTransition, now can be used with async func

Summary

Documentation advises against using async functions inside startTransition. However, in the newest changelogs, that has changed, and we can now easily use async functions inside startTransition. Perhaps I misunderstood it.

Details

If you read the documentation on react-dev, you can find information about startTransition. However, when you check the changelog on the react GitHub, you will find information about adding an option to use async functions at.

打开 react.dev 上的 startTransition 参考页面，并将其中关于异步函数的指南与 CHANGELOG-canary.md 中 2023 年 10 月 5 日的对应条目进行比较。确认文档是否已经过时，然后更新页面，使其指南与当前行为和 changelog 保持一致；当有关异步函数的建议准确无误时，工作就完成了。
