hashicorp: auth/create/token returns warning if data.meta exists and display_name not set

[noahehall]

• @see vault /auth/token/create returns ignoring unrecognized parameters [meta] when creating token hashicorp/vault#18550
• the token still gets created, so report the issue and move on
• im not even sure where the display_name is supposed to be viewed so ignore that too
  • haha display name is returned when you lookup the token, but not in the response
