roof removal: change override.json file extension to .jsonc

JSON itself doesn't natively support true comments (the official way is
to include it as data), which means that every syntax highlighter wants
to scream when it reads the file, despite the fact that GSON ignores
comments perfectly fine. JSONC however supports true comments, and is
supported by all the syntax highlighters we use (GH, IJ), while also
staying as entirely normal JSON otherwise.
