homebrew 镜像帮助更新

[silverbzez]

• brew 4.0.22 移除了对homebrew-cask-drivers仓库的支持，关于仓库的设置命令均会报错，因此移除文档内对此仓库的设置命令。 参考Homebrew/brew#15535 报错内容： Error: homebrew/cask-drivers was deprecated. This tap is now empty and all its contents were either deleted or migrated.
• 置顶所有有关brew版本更新引起的镜像变化的注解
• 增加Linuxbrew下homebrew-services仓库的设置命令。经过测试，homebrew-services已在systemd/Linux下可用。
  • 测试环境：Debian 11, Ubuntu 20.04, Ubuntu 22.04, Fedora 37
  • 测试bottle：syncthing，unbound
• 分离<复原仓库上游>章节下Homebrew与Linuxbrew共用的codeblock，以免引起误解

guys, feel free to move this pr to another repo if i went for the wrong one. it's rather confusing with either updating this -web repo or another -help repo. apologies in advance.

目前 homebrew 部分由于技术上的原因，是两边分别维护的，也就是说两边都需要这个更改；等我回到电脑边会合并这个 PR
