下載指定版本 Chromium 與其 Webdriver

以下載 Linux 平臺 119 版本 Chromium 與其 Webdriver 爲例：

首先在 Chromium 版本發佈頁 找到想要下載版本的 Branch Base Position 比如 1204232。然後在 https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Linux_x64/ 中搜索 1204232。如果發現搜索結果爲空，不用怕，把最後一位去掉試試，這時就會搜到 1204234。也可以再刪掉一位，就會出來更多相近的結果。點進去後下載 chrome-linux.zip 和 chromedriver_linux64.zip 就可以了。

unzip chrome-linux.zip
cd chrome-linux
#查看 Chrome 版本
./chrome --version
#Chromium 119.0.6045.0
