Draft: Temporarily reduce o11y authTokens validation requirements

What does this MR do and why?

Temporarily reduce authTokens validation requirements

We're updating the authentication process for the observability app, and an interim change is to reduce the validation requirements for the authTokens prop so that when we update the service and it returns less properties, we don't break the app.

This will be reverted in a follow-up PR after we update the service to return the required properties.
