根据当前浏览器版本，下载或更新驱动文件为对应的版本

以前通过ChromeDriverManager().install()的方式自动下载驱动的方式，现在行不通了，访问不通下载网址，会报错：requests.exceptions.ConnectionError: Could not reach host. Are you offline?

所以想着换一个下载地址和方式，通过国内的镜像https://registry.npmmirror.com/binary.html?path=chrome-for-testing/下载。

通过接口返回分析发现该网站获取驱动版本的地址为：https://registry.npmmirror.com/-/binary/chrome-for-testing/ ，最终的下载地址前缀为 https://cdn.npmmirror.com/binaries

于是有了下面 的代码，通过windowsAPI获取安装的浏览器的版本，通过上面的地址获取浏览器驱动版本列表信息，找到与浏览器大版本号相同的最新版本的驱动版本，拼接成最终的下载地址。下载驱动压缩包，用解压缩出来的驱动exe文件替换原来的旧文件，然后删除解压缩文件和下载的压缩文件。
