adds fishing category to games vendor (#86699)

## About The Pull Request
this pull request adds a fishing category to the games vendor with items
that cost 50 credits more than their goodie alternatives.
## Why It's Good For The Game
this allows people to start their fishing goals earlier without waiting
20 minutes for cargo at the caveat of the items costing 50 credits extra
than normal
