Prisma Schema Language (PSL) user-defined language

[geket]

Foreword & Motivation

While building a TypeScript based ecommerce platform for a client, after I changed our current SQL seed integration and went to mess around with the Prisma schema, I noticed Notepad++ was not formatting or allowing me to collapse any part of the code. Upon checking for the best language to use to exhibit similar behavior, I noticed I could define a language and remembered not too long ago I followed NPP on Github. I figured why not see what I could do here.

I went ahead and I made one for NPP, I've been using your wonderful software for years and I figured I'd contribute at least something, thanks for all your hard work fellow devs.

I made an issue at first before I realized I could make a PR, #358 which I closed. Happy to make any changes to fix any nits.
