APIv2: Make sure tripStep is well defined in the docs

[tahini]

See screenshot. I would expect to have the definition of the tripSteps here, not just an empty array. There's probably something missing in our doc to make the link.

Running redocly cli (via https://redocly.com/docs/cli/installation/) lint gives nothing related to that (many other error but nothing about steps

[tahini]

Would it then be too deep in the hierarchy? Or too complex to describe? But indeed the example output gives something plausible, so not sure why it's like this...

[greenscientist]

Current guess: something about the discriminator might not work at that level or is missing information

[greenscientist]

Ou bien qqch avec le path de la référence. C'est juste weird que les tools ne donne pas d'erreur.

swagger-ui seems fine with it. https://petstore.swagger.io/?_gl=1*mz8a3z*_gcl_au*MzM0OTc0MTguMTcxMjg2ODEwMg..&_ga=2.60220772.872043090.1715623353-1558485238.1712868102#/default/get_v2_route

Tested with this tool: https://authress-engineering.github.io/openapi-explorer/?#?route=get-/v2/route
and it's there. So something is making redoc unhappy
