ISC DHCP (and OpenVPN) update

pfSense 23.09.1 (and pfSense 2.7.2 CE) uses the pfSense (Netgate) repositories.
So, if Netgate incorporated these upgrades into the pfSense repository, then you can be pretty sure they are meant to be used.

Installed packages to be UPGRADED:
        curl: 8.4.0 -> 8.5.0 [pfSense]

So, its console time, option "13" or option "8" and then

pkg update
pkg upgrade
