fix(ci): 翻译回推 commit 移除 [skip ci] (#41)

PR #40 实测发现:bot 回推的翻译 commit 带 `[skip ci]`,把新 SHA 上所有 workflow
都压掉了,必需检查(validate/translate/wait-for-copilot-review)永远不报告,PR 反而无法合并。

- 防循环不依赖 `[skip ci]`——translate job 的 bot actor 判断已经保证(bot 触发时 job
skipped,而 skipped 满足必需检查)
- validate / copilot 本来就应该在翻译产物上重跑
- 已加注释防止回归
