Desired State

Description of the change you are proposing:

I know it's because of #1030, we archived history documents to avoid unnecessary builds, but it leads to some links 404.

If we want to fix this problem:

1. Server redirects: but the ASF Infra can't set up specific rules for this site.
2. Put history documents in the asf-site branch and don't use force-push when publishing.
3. Update sitemap.
