[OpenVPN Deprecation] Upstream Rafficer/linux-cli-community will stop working on 31 March 2025

[kohane27]

First of all, let me just say that I'm very thankful for this repo. Running Proton VPN inside the docker is very useful and fits my use case. It's served me well for more than a year. So thank you!

However, sad news: From Deprecation notice

Proton VPN is upgrading its OpenVPN infrastructure. This means the legacy OpenVPN configuration will stop working on 31 March 2025. After this date, you’ll need to switch to the official Proton VPN for Linux app, or reconfigure OpenVPN or WireGuard manually.

Should we at least warn potential new users in the README.md or even archive this repo? Thank you!
