Add new line before field description

[emilkholod]

If we will generate SDL schema then we get:

"""Desc 1"""
type Object1 @key(fields: "field1") {
  """Desc field 1"""
  field1: DateTime
  """Desc field 2"""
  field2: ID
  """Desc field 3"""
  field3: String
  field4: String
  field5: String
}

but by default there should be a new line before descriptions:

"""Desc 1"""
type Object1 @key(fields: "field1") {
  """Desc field 1"""
  field1: DateTime

  """Desc field 2"""
  field2: ID

  """Desc field 3"""
  field3: String
  field4: String
  field5: String
}
