[BUG] Fresh install on FreeBSD 14.1: jails cannot access internet via the host

[MANDATORY] Describe the bug [MANDATORY] Bastille was running just fine on a FreeBSD 14.0 host. I upgraded the host to 14.1 and all jails lost access to the internet. To verify that this was not something specific to that one host, I tried again with a fresh install of bastille on a fresh 14.1 install on a VM. Same behavior.

[MANDATORY] Bastille and FreeBSD version (paste bastille -v && freebsd-version -kru output)

0.10.20231125
14.1-RELEASE
14.1-RELEASE
14.1-RELEASE

[MANDATORY] How did you install bastille? (port/pkg/git)

pkg

[optional] Steps to reproduce?

Install FreeBSD 14.1 or upgrade existing host to 14.1.
Install bastille from pkg/latest.
Follow bastille's Getting Started guide, including pf.conf.
Create new jail.
Attempt to pkg install ....
See below. Host resolution fails.
