set cypress mirror url in .npmrc what's the prefix name?

[lanseria]

Current behavior:

registry=https://registry.npm.taobao.org
disturl=https://npm.taobao.org/dist
chromedriver-cdnurl=https://npm.taobao.org/mirrors/chromedriver

Desired behavior:

cypress-binary-host-mirror=https://npm.taobao.org/mirrors/cypress{version}

is right?

You should use the same wording as environment variables as mentioned here #1399

cypress_download_mirror=

I opened an issue to add this to the docs
