Confirm the unconfigured Snort package was actually removed from morpheus

[Gerrrt]

ADR-0006:49:

The unconfigured Snort package is removed rather than left installed.

There is no evidence this happened, and
docs/runbooks/enable-suricata.md:30
still lists removing it as a prerequisite — which suggests it is still
there.

Small, but worth closing out properly:

• Two IDS packages installed on the same firewall is a configuration that
  invites someone to enable the wrong one at 1am.
• An unconfigured package still receives updates and still has attack surface,
  on the device that terminates every VLAN.
• The ADR asserts it as done. Either it is, and the runbook prerequisite should
  go; or it is not, and the ADR is describing an intention as a fact.

Needs one look at the pfSense package list to resolve, and then an edit to
whichever of the two documents turns out to be wrong.
