Added missing gardening supplies to Tramstation. (#71027)
Added missing gardening supplies to Tramstation. (#71027)

## About The Pull Request

Tramstation's garden, unlike the garden on every other station, does not
have any watering cans or bottles of nutrient. I've added one watering
can and one each of E-Z Nutrient and Robust Harvest to bring it in line
with the other maps.

## Why It's Good For The Game

Consistency is good, in terms of what items are supplied in what room.
Also, without these items it's much more inconvenient to use
Tramstation's public garden, which doesn't seem to be intended.
