Correct Upgrade Description

[houseofyin]

The rewardDescription in flagship/src/app/campaign/management-phase/management-phase.component.ts renders as something like:

5 point Weapons Team upgrade

The way that reads, it seems like only a single upgrade card can be gained. However, in the rules under Location Rewards -> Upgrades (p21) it reads:

"That player may purchase upgrade cards of the chosen type"

So I think point ${reward.upgradeType} upgrade should be changed to points of ${reward.upgradeType} upgrades in rewardDescription
