Update Create & Get One endpoints response structures

[kelsey-steven-ada]

Asana Task

Solution branch used to test CLI and test updates

Changes

• Removes outer "task" and "goal" wrappers for create and get one route responses
  • Updates Wave docs
  • Updates tests
  • Updates CLI to no longer look for "task" wrapper in parse_task_from_response
• Small updates to wave doc organization
  • Pulls general testing info that is similar between waves out of the tips sections so that "Tips" is more focused on info specific to each wave.
  • There was a lot of information around helper functions that was repeated on every relevant endpoint. Repeated info was moved into the tips section to help folks have a clear place to look for that info and hopefully suss out the requirements/new information easier since they aren't skimming through repeated info.

Overall, this looks good! I noticed one extra place where we could remove some redundancy and then just a couple of other small changes that might make everything a little more clear!

Looks good to me!
