invalid JSON is being produced once formatted about mdsf HOT 4 CLOSED

The reason json is formatted as jsonc is because people often have comments in their json codeblocks, which isn't part of the specification.

But I just did a quick test and it seems that both prettier and deno supports formatting json files with comments. Sadly Biome does not expose the argument for allowing comments (https://github.com/biomejs/biome/blob/a6f5f0e8187912b389bf88ece65a51f1e02027a6/crates/biome_service/src/configuration/json.rs#L31).

I was already planning on introducing language “flavors” (css -> css, scss, sass, less, json -> json, jsonc, json5, sh -> sh, zsh, bash), which should fix the issue.

The point I raised in #146 is interesting here as I have no way to know what formatter is being applied.

It seems to me you are using jsonc format which supports comments and extra trailing comma

These two formats should be handled separately.

```json
{
        "foo": "bar",
        "user_id": "2313",
        "scope": ["internal"]
}
```

```jsonc
{
        "foo": "bar",
        "user_id": "2313",
        "scope": ["internal"] // some comment
}
```

it might be related to this prettier/prettier#15956

so you will have to allow "allowTrailingCommas" for jsonc formatter and allowTrailingCommas=false for regular json

Or maybe the "bug" is already fixed, are you up 2 date on prettier ?
