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.

self-hosted runner のセクションにある docs/advanced-usage.md を更新します。Windows ユーザーが必要な証明書をどこから取得できるか、どのようにインストールするか、また「unable to get local issuer certificate」エラーに対して runner が証明書を見つけられるように設定する方法を説明します。手順が要求された 3 つのステップすべてを扱い、self-hosted Windows runner 上で actions/setup-python@v4 workflow が動作するようにすることが完了の条件です。
