I think it's because the branch name has changed.

apisix-website: https://github.com/apache/apisix-website/blob/master/doc/docusaurus.config.js#L11-L12.
apisix-ingress-controller：https://github.com/apache/apisix-ingress-controller/blob/master/.asf.yaml#L46-L51

In git's model, branches and tags have little difference. The real problem seems to be the website script does not search fort he git-tag paths.
