Thank you for this neat generator!

When I tried using it with Prisma 4.10.1 and pnpm, I was getting an error that mmdc command failed.

Command failed: ../../amsterdam/node_modules/mmdc -i /var/folders/lk/g24rtghs1gn_6l6tc9tcdnmm0000gn/T/prisma-erd-UdJgkH/prisma.mmd -o /Users/maticzavadlal/Code/mine/amsterdam/server/prisma/ERD.svg -t forest -c /var/folders/lk/g24rtghs1gn_6l6tc9tcdnmm0000gn/T/prisma-erd-UdJgkH/config.json

After looking into the problem, I was able to resolve it by adding an explicit dependency to @mermaid-js/mermaid-cli.

The installation step says to install this as a dev dependency already.
