Custom Prisma Client context key

By default, typegraphql-prisma looks in runtime for Prisma Client in the GraphQL context under the prisma key.

However, in some cases like when you have multiple Prisma clients generated, you can provide a generator option to set the custom key for context object, where the Prisma Client can be found:

generator typegraphql {
  provider         = "typegraphql-prisma"
  contextPrismaKey = "customPrisma"
}

By using this option, all the generated resolvers will try to use the Prisma Client from context["customPrisma"] instead of the standard context.prisma.
