docs: 翻掉我上轮漏掉的三处，并修正发布说明里一条错误建议

上一轮我说"剩余中文都合理"，说得太满。这三处不合理：

1. bootable/linux-setup/test-installation.sh —— 在用户的 Linux 机器上跑的
   自检脚本，输出中英混杂（check "安装目录存在" ... "Directory $INSTALL_DIR"）

2. issue / PR 模板 —— 贡献者第一眼看到的东西，而 CONTRIBUTING.md 已经是
   英文了。顺带修掉模板里指向上游官网和上游微信的链接（那些我们控制不了），
   改为指向本仓库。PR 模板加了一条"说明你在哪个平台跑过" —— 只在 Mac 上
   验证过的 .bat 改动一直是本项目最主要的故障来源。

3. release.yml 的发布说明正文 —— 那是用户在 release 页面读到的文字，内容
   还停留在旧产品（DeepSeek/通义、预装微信 QQ 钉钉飞书企微）。

第 3 项里还有一条**和事实相反**的建议：它让用户把 U 盘格式化成 NTFS。
macOS 对 NTFS 只读，照做正好会让"配置跟着盘走"这个核心卖点在 Mac 上
彻底失效。改为 exFAT，并说明为什么慢、以及我们如何用本机缓存补偿。

track-upstream.yml 的输入描述和输出也翻了 —— 它们会显示给手动触发
workflow 的人。
