Demo-skills-test is currently commented out

# Problem

`tests/integration/components/demo-skills-test.js` is currently completely commented out. We need to figure out why we commented it out, and work on either removing, or uncommenting it.

從 tests/integration/components/demo-skills-test.js 開始，調查為什麼整個檔案都被註解掉了。檢查周圍的 integration-test 設定和 repository 歷史記錄，以確定其被停用的原因。完成的標準是刪除過時的測試，或將其還原為作用中的測試，並由調查結果說明所選擇的處理方式。
