Support for syntax highlighting for Prisma schemas

[nikolasburk]

Is your enhancement request related to a problem? Please describe.

Prisma is a database toolkit that comes with its own data modeling language to define the so-called Prisma schema.

Right now, Prisma schemas don't have proper syntax highlighting in dev.to articles because their syntax highlighting is based on rouge.

Describe the solution you'd like

Ideally, dev.to could support the prisma annotation on fenced code blocks to render Prisma schemas more colorful! For example:

```prisma
datasource db {
  url      = env("DATABASE_URL")
  provider = "postgresql"
}
generator client {
  provider = "prisma-client-js"
}
model User {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  email     String   @unique
  name      String?
  role      Role     @default(USER)
  posts     Post[]
}
model Post {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  published Boolean  @default(false)
  title     String
  author    User?    @relation(fields: [authorId], references: [id])
  authorId  Int?
}
enum Role {
  USER
  ADMIN
}
```
