Make it possible to have .env file in same directory of prisma.yml when in a sub directory

[timsuchanek]

Lets say I have this folder structure:

.
├── .graphqlconfig.yml
└── app
    ├── .env
    └── prisma.yml

Right now the extension doesn't evaluate the .env file.
This is an issue in prisma-yml
