windows wsl2 中打开rust std 本地文档

https://github.com/rust-lang/rustup/issues/2206#issuecomment-1833076438

Adding the prompt below in .zshrc or .bashrc:

export BROWSER="/mnt/c/Program Files (x86)/Google/Chrome/Application/chrome.exe"

It works for me. Maybe you should alter the real executing path of browser.
