ros generate service <service name> is currently breaking

[rpbaltazar]

when running ros generate service <service name> it tries to start a new application using rails 6.0.0 instead of the 6.0.0.rc2 that we currently use in our services. This then fails because apartment gem is not yet supporting rails 6 creating a breaking dependency.

Either we help on ensuring apartment supports rails 6, or we will have to run rails _6.0.0.rc2_ new <service name> when trying to generate the ros service to ensure that it is initialised with the rc2 version instead of the 6.0.0
