Adds MREs to the ColMarTech Food Vendor (#7111)

# About the pull request

Adds 15 MREs to each ColMarTech Food Vendor on the Almayer

# Explain why it's good for the game

Marines basically already get infinite MREs anyways, no harm in adding
them if shipside personnel like MPs want to grab food on the go and not
have a whole plate of food just in their bag, which is weird.
