Skyhigh173/json: rename blocks for consistency (#1013)

- made booleans internally consistent with missing question marks
- removed "get" where applicable
- made some blocks be more internally consistent when it comes to value order, like putting the array before the new value
- removed unnecessary words like "content" in the list block
