Note that the OpenVPN example repository is archived

[5h4d0wn1k]

Why:

Closes: #45946

The codespaces-contrib/codespaces-openvpn repository referenced from this article is archived and no longer maintained. Combined with the existing warning for the GitHub CLI extension (#32221), readers now have no non-archived walkthrough to follow, so the article should flag that the linked example is defunct rather than presenting it as current guidance.

What's being changed (if available, include any code snippets, screenshots, or gifs):

Adds a warning note to the "Using a VPN to access resources behind a private network" section, mirroring the warning already used for the GitHub CLI extension on the same page:

> [!WARNING]
> The linked example repository is archived and is no longer maintained.

The issue hasn't been marked ready for community contributions, so I'm afraid I'm going to close this out in case we need to explore a different solution (we haven't been able to make that determination yet).

Understood — thanks for the transparency on this. I won't reopen, and no action needed from me. If the docs team settles on a preferred direction for this page, I'm happy to contribute to it.
