doc(GTFS): profile name in api docs CUSTOM_KEYS

[takb]

• Reason for change:
  Old profile names were still used in the CUSTOM_KEYS references

[TheGreatRefrigerator]

i still found these, do they also need adjustment?:

• https://github.com/GIScience/openrouteservice/blob/master/openrouteservice/src/main/resources/resources/locales/ors_de-DE.resources#L94
• https://github.com/GIScience/openrouteservice/blob/master/openrouteservice/src/main/resources/resources/locales/ors_en-US.resources#L94
• https://github.com/GIScience/openrouteservice/blob/master/openrouteservice/src/main/java/org/heigit/ors/api/responses/routing/json/JSONLeg.java#L38
• https://github.com/GIScience/openrouteservice/blob/master/openrouteservice/src/main/java/org/heigit/ors/api/responses/routing/json/JSONLeg.java#L112

For the locales, only US and DE are added for the public transit, not sure if there are other languages should also have the pt object.

I don't think we need to use the full profile name for these four strings you mention, the language file key is something internal and the leg type value for the responses only produce unnecessary bloat.

For the locales, only US and DE are added for the public transit, not sure if there are other languages should also have the pt object.

But you are right about this, I'll add untranslated values to the other language files. Thx for the heads-up!
