What happened:
@wenxuwan found that the link in the sidebar is wrong, see https://mosn.io/layotto/#/zh/design/oss/oss-api-design

The problem is that our deadlink checker didn't find it :(
The checker runs successfully without noticing this link:
https://github.com/mosn/layotto/actions/workflows/dead-link-checker.yaml

What you expected to happen:
deadlink checker should find out the wrong urls

How to reproduce it (as minimally and precisely as possible):
open https://mosn.io/layotto/#/zh/design/oss/oss-api-design

Anything else we need to know?:
