[BUG] Table entry is missing for VNET jails

[KizzyCode]

[MANDATORY] Describe the bug [MANDATORY]
Bastille does not create an entry in the pf-table jails when starting a VNET jail.

[MANDATORY] Bastille and FreeBSD version (paste bastille -v && freebsd-version -kru output)
0.8.20210115
12.2-RELEASE-p3
12.2-RELEASE-p3
12.2-RELEASE-p3

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

[optional] Steps to reproduce?
Create a new VNET jail using bastille create --vnet alcatraz 12.2-RELEASE 10.0.1.10/24 em0, then display the jails-table using pfctl -t jails -T show.

[optional] Expected behavior
Bastille should add the jail's IP to the jails-table upon start.

[optional] Screenshots
None

[optional] Additional context
My current workaround is to use nat on $ext_if from em0bridge:network to any -> $ext_if as generic rule, but a table based solution would be better IMO.
Maybe this bug is related to #80, however the bastille version used is much newer than 0.5.20191128.
