Do not copy unnecessary cache file

[conico974]

We should not copy and delete file there

opennextjs-aws/packages/open-next/src/build/createAssets.ts

Lines 75 to 89 in 73281c9

	const outputPath = path.join(outputDir, "cache", buildId);
	[".next/server/pages", ".next/server/app"]
	.map((dir) => path.join(dotNextPath, dir))
	.filter(fs.existsSync)
	.forEach((dir) => fs.cpSync(dir, outputPath, { recursive: true }));
	// Remove non-cache files
	const htmlPages = buildHelper.getHtmlPages(dotNextPath);
	buildHelper.removeFiles(
	outputPath,
	({ relativePath }) =>
	relativePath.endsWith(".js") ||
	relativePath.endsWith(".js.nft.json") ||
	(relativePath.endsWith(".html") && htmlPages.has(relativePath)),
	);

Ideally, we should also add a revalidate value (from the prerender manifest) here
