Describe the bug
otp_make_config("otp") does not list 'otp' options - produces same output as otp_make_config("router")

reproduction:

if(!require('opentripplanner')) {
  install.packages('opentripplanner')
  library('opentripplanner')
}

if(!require('jsonlite')) {
  install.packages('jsonlite')
  library('jsonlite')
}
{
  print("=====")
  print("opt.json")
  print(toJSON(otp_make_config("otp"), pretty=TRUE, auto_unbox = TRUE))  
  print("=====")
  print("router.json")
  print(toJSON(otp_make_config("router"), pretty=TRUE, auto_unbox = TRUE))  
  print("=====")
  print("build.json")
  print(toJSON(otp_make_config("build"), pretty=TRUE, auto_unbox = TRUE))  
  print("======")
}

If you want to use otp v2.3 then you need to do otp_make_config("otp", version = 2)

[mem48]

The opentripplanner package is still mostly focused on OTP v1.5 because of the additional analysis features that are in v1.5 and were removed for v2.

See https://docs.ropensci.org/opentripplanner/articles/OTPv2.html

Note OpenTripPlanner is undergoing some significant changes at the moment with features being added and removed. To avoid constant updates to the R package we are currently targeting support at v1.5 and v2.2. Other versions may work but are not officially supported.
