Advise users of self-hosted Windows runners how to resolve: "unable to get local issuer certificate" error

I'm using a self-hosted Windows 10 runner with GHES 3.6.5. The actions/setup-python@v4 step in my workflow fails with:
unable to get local issuer certificate. I presume I need to get a certificate from the server somewhere, install it in Windows and tell my self-hosted runner where to find it. But the instructions at https://github.com/actions/setup-python/blob/main/docs/advanced-usage.md#using-setup-python-with-a-self-hosted-runner do not say anything about certificates.

Description:
Add a section to the instructions for the setup-python action (possibly at https://github.com/actions/setup-python/blob/main/docs/advanced-usage.md#using-setup-python-with-a-self-hosted-runner) to explain how to resolve the unable to get local issuer certificate error. E.g., Please explain:

1. Where to get the certificate(s) from.
2. Where/how to install the certificate(s) in Windows.
3. How to configure a self-hosted runner so that it can find the certificates.

Justification:
Get the setup python task to work.

Are you willing to submit a PR?
No, sorry.

更新 docs/advanced-usage.md 中关于 self-hosted runner 的部分。说明 Windows 用户可以从哪里获取所需的证书、如何安装证书，以及如何配置 runner，使其能够针对“unable to get local issuer certificate”错误找到这些证书。完成的标准是：说明涵盖要求的全部三个步骤，并帮助 actions/setup-python@v4 workflow 在 self-hosted Windows runner 上正常运行。
