Steps to reproduce the bug:

1. Clone this repo
2. Run npm install
3. Run node printSchema.js to print the schema using the graphql package's printSchema() function, which should produce output like the following:

$ node printSchema.js
type Book {
  """
  multiline
  Book.dummy
  description
  """
  dummy: String
}

"""
multiline
Query
description
"""
type Query {
  books: [Book]
}

4. Run node server.js to start the local ApolloServer
5. Run npx -p @apollo/[email protected] rover graph introspect http://localhost:4000 to print the schema using the Rover CLI, which should produce output like the following:

$ npx -p @apollo/[email protected] rover graph introspect http://localhost:4000                          
Introspection Response: 

"""Exposes a URL that specifies the behaviour of this scalar."""
directive @specifiedBy on SCALAR
type Book {
  """
  multiline
Book.dummy
description
  """
  dummy: String
}
"""
multiline
Query
description
"""
type Query {
  books: [Book]
}

Note that the inconsistent leading whitespace is the multiline comment on the Book.dummy field.
