Subject: [PATCH] refactor(v2): convert synchronous file write to asynchronous
 (#2936)

* perf(v2): convert synchronous filewrite to asynchronous in feed file generate

This looks like should return a Promise list , other than a sync io operation

* perf(v2): convert synchronous filewrite to asynchronous in sitemap generate

* perf(v2): convert  Promise style to async/await style

for consistency
