The details

Resolves

Needed for RaspberryPiFoundation/blockly-keyboard-experimentation#727

Proposed Changes

• Makes callbackKey public
• Reformats the code where it's set to be less weird
• Updates the comments with better reasoning for why we look for both properties in the json

Reason for Changes

The comment implies that we only check the lowercase version because of IE11, but that can't be correct, because the ButtonInfo type definition uses the lowercase version, despite our docs saying to use the camelcase version. We have supported both for a long time and should continue supporting both.
