Makes syndi-mod in Tactical NukeOps Metagame Syndi-kit unrestricted with access. (#75696)

## About The Pull Request
Basically someone forgot to make it unrestricted or add agent's card to
the kit so it would be usable when mods were added.
## Why It's Good For The Game
1 more thing that works as intended?
## Changelog
🆑
fix: Syndicate mod-suit in Tactical NukeOps Metagame Syndi-kit (the one
with bulldog shotgun) now doesn't require any access, so you don't need
to buy agent card to simply use it.
