openconnect: update vpnc-script version
openconnect: update vpnc-script version

Fixes https://github.com/Homebrew/homebrew-core/issues/94622.

The 'vpnc-script' used in this formula is quite old. Recent versions have updated support for IPv6, in particular, and should be backwards-compatible with OpenConnect v8.10.

Closes #94625.
