Feature: provide curriculum APIs

**Which module(s) and week(s) does this change affect?**
Module(s): all
Week(s): all

**What is the work that needs to be done?**

- Create some static JSON apis for trainees to interact with using real curriculum data
- I could probably also use one in the offline caching strategy
- Hugo supports alternative output formats
- Just need to write some .json layouts in layouts/_default/

**Why is this work important to do?**

It's not it's just it would be good to have some static apis to look at directly and connect instantly to a front end and it's easy to generate this right in the platform
