rename to "vp_tokens" from "vp_token" to make clear it is an array

[Kristina Yasuda]

Suggest renaming “vp_token“ to "vp_tokens" in the response to make clear it is an array.

[Kristina Yasuda]

initial use-cases seem to be vp_token including only one VP.

+ even when there are multiple VPs, there is still only one VP_token

I am ok with resolving this at the next SIOP call

On 2021-11-25 SIOP call, we discussed that making it plural vp_tokens (or vps_token) would be good to clarify that it can be an array.

[Kristina Yasuda]

keeping it vp_token since the text clearly says it is an array

Like aud, which can be an array, it’s fine for the name to remain singular.
