Update Docstring for routes.py

[TimothyXu]

As a Developer I need understand what functionalities our API offers by reading the code So that that I can use it to perform business operations.

Details and Assumptions

• We need to use comments and docstrings in our code especially routes.py to explain our service
• [EDIT]: we can probably just explain how to honcho start then just ask the person to read .../apidocs instead?

Acceptance Criteria

 Given the Flask server is running
 When we read the doctoring of routes.py
 Then we see a brief description of our routes

Per HW1 the root url response needs to be: the name, version, and what your resource URL is. We already have these so don't need to update the root URL response but the docstring still needs to be updated

[yjjw]

Actually I think after we refactored the code to RESTX, the comments we have is already self-explanatory and sufficient? I personally don't think we should explain how to honcho start in our code file (should be in README), what do you think?

I agree we mostly don't need to do anything. There are some minor typos/errors I'll fix in like 30 minutes
