Develop schema and basic GitHub Action

[dluman]

Create an example GatorGrader file for allowing instructors to develop achievement "badges" (the whorl-server's badger API endpoint). These badges should have a few possible properties:

1. Badges can be "one-off"s (e.g. only one check needed to achieve)
2. Badges can be spread across multiple grader objectives (i.e. need two or more checks to achieve)
3. Badges can be spread across multiple assignments (i.e. a series of different assignment checks can collectively achieve a larger "badge")

This action must be developed using GitHub Actions and nodejs. A prototype for how this action might work exists as Wizard. This project should leverage ncc to create a CJS (common JS) file from which the action should run. The linked repository (Wizard) does this.
