Modsuit actions no longer go on cooldown when selected (#87396)

## About The Pull Request

Modsuit actions no longer go on cooldown when selected, only when
actually used. So you can select an action and use it
## Why It's Good For The Game

I don't even know why this was a thing it just makes modsuits more
uncomfortable and unpleasant to use. I see no reason for it to exist so
i'm removing it. @Fikou
