prefetch-yarn-deps: Fix access to `.resolved`

const prefetchYarnDeps = async (lockContents, verbose) => {

	const lockData = lockfile.parse(lockContents)

	const tasks = Object.values(

	await performParallel(

		Object.entries(lockData.object)

		.map(([key, value]) => {

			return { key, ...value }

		})

		.reduce((out, pkg) => {

			out[pkg.resolved] = pkg

			return out

		}, {})

		.map(([key, value]) => () => downloadPkg({ key, ...value }, verbose))

	)

		.map(pkg => () => downloadPkg(pkg, verbose))

	await performParallel(tasks)

	await fs.promises.writeFile('yarn.lock', lockContents)

	if (verbose) console.log('Done')
