graphql: schema.graphql generation broken after update

Bug Report

Currently the schema.graphql still uses multiline comments, which leads to an error in my tests.

Current behavior

GraphQLError: Syntax Error: Unexpected BlockString "What change was done?".

Input Code

registerEnumType(AuditAction, {
  name: 'AuditAction',
  description: 'What change was done?',
});

Output schema.graphql

"""What change was done?"""
enum AuditAction {
  APPROVED
  ASSIGNED
  ...
}

Expected behavior

# What change was done?
enum AuditAction {
  APPROVED
  ASSIGNED
  ...
}

Possible Solution

Genrate correct comments with # instead of """? At least when I do a search and replace, it does work indeed. Which package is responsible for generating that?
