Summary

fetchpriority was added as a support option as part of https://github.com/react/react/pull/36835, so docs should be updated to include it.

Details

Add an options value for fetchpriority
something like :

fetchPriority: a string. Suggests a [relative priority for fetching](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Attributes/fetchpriority) the script. Its possible values are auto, high, and low.

I am not sure if this needs a canary/experimental badge because this is a very new change

開啟 react.dev/reference/react-dom/preloadModule#reference 中的 preloadModule 參考頁面，並查看其中如何記錄各個選項。新增 fetchPriority 選項及其可能的值和連結的優先級說明；當轉譯後的參考頁面包含此項目，且 experimental-status 問題已依照與該頁面一致的方式解決時，工作即告完成。
