REGRESSION: Missing headless support

[cmars]

Cannot connect to Proton VPN on a headless server.

System is debian based. Installed protonvpn-cli and it doesn't work at all.

This is a massive regression in the CLI from the prior version, which did not have this problem.

Proton: "The Proton VPN Linux CLI is intended for every Proton VPN service user"

Scam alert! Proton too: "[...]Doesn’t run on headless servers."

It's NOT a CLI, they use the keyring of Gnome!!!
