Boolean toggle not showing up for JSON document

[jeffpyke]

Steps I took:
Added a JSON document to my project.
Opened that in forestry.io without a template.
Created a frontmatter template in the forestry UI.
Added boolean fields to the template under repeatable field group.

Expected:
The boolean toggles should show up when editing the JSON document.

Observed:
The boolean toggles are not showing up when editing the JSON document.
