What happened?

I'm receiving Expected an array, an object, or a literal but instead found whenever I add a comment to a JSONC file. Repro.

Here's my biome.json:

{
	"$schema": "./node_modules/@biomejs/biome/configuration_schema.json",
	"files": {
		"ignoreUnknown": true,
		"maxSize": 10485760
	},
	"formatter": {
		"lineWidth": 110
	},
	"javascript": {
		"formatter": {
			"arrowParentheses": "asNeeded"
		},
		"parser": {
			"unsafeParameterDecoratorsEnabled": true
		}
	},
	"json": {
		"formatter": {
			"trailingCommas": "none"
		},
		"parser": {
			"allowComments": true,
			"allowTrailingCommas": true
		}
	},
	"linter": {
		"enabled": true,
		"rules": {
			"recommended": true,
			"a11y": {
				"useKeyWithClickEvents": "off"
			},
			"security": {
				"noDangerouslySetInnerHtml": "warn"
			},
			"style": {
				"noNonNullAssertion": "off",
				"noParameterAssign": "warn",
				"useSingleVarDeclarator": "off"
			},
			"suspicious": {
				"noExplicitAny": "off"
			}
		}
	}
}

Expected result

It should allow comments at least in JSONC format.
