deepin pr auto review

关键摘要:

• 在debian/changelog文件中，版本号更新应该使用dde-daemon (6.0.40)的格式，而不是dde-daemon (6.0.40) unstable。
• 在debian/changelog文件中，应该添加新的提交摘要描述新版本的变更。
• 在misc/dde-daemon/keybinding/system_actions.json文件中，deepin-terminal --quake-mode命令被替换为dde-am deepin-terminal quake-mode，需要确认新命令是否正确且包dde-am是否已安装。

是否建议立即修改:

• 是
