Run React-lua tests in CI

This is blocked by Jest-lua; we are waiting on Roblox to release their repo.

We want to run the React-lua test cases in CI with Jest. This would be a significant achievement for the project, as it would be the very first substantial Roblox package to run its tests in GitHub CI without mocking any Roblox environment.

首先確認 Jest-lua 相依性和預期的 Roblox 儲存庫版本是否可用。接著檢查專案的 GitHub CI 設定和 React-lua 測試案例，以判斷 Jest 應如何在不模擬 Roblox 的情況下執行這些測試。完成的標準是測試案例能在 GitHub CI 中針對真實的 Roblox 環境成功執行。
