Add two (2) combat gloves to the secvend (#5556)

## Short description
As titled

## Why we need to add this
The gloves were added and never increased over one year and a half ago
:#185
Nowadays every sec shift start by a few bolting to an atm and getting
the gloves, they are gone in less than a minute into the shift.

Since sec population has definetly increased since then i think its only
fair to scale them, its only two more which is like a firth of the sec
departement.
Even Medwia agrees, suprisingly.
