FEATURE REQUEST rebundle modified front-matter object into markdown

[dimaslanjaka]

i was trying modify date from attribute.

console.log(`File: ${file}, Creation Date: ${creationDate}`);
	const read = fs.readFileSync(path.join(process.cwd(), file), {
		encoding: "utf-8",
	});
	try {
		const parse = fm(read);
		parse.attributes.date = creationDate;
		console.log(parse);
	} catch (error) {
		console.error(`fail parse ${file}`);
	}

the main problem is, how to rebundle into markdown front-matter format ?
