The “last update time of this doc” at the bottom of docs under the site may have a problem

[rayowang]

What happened:
The “last update time of this doc” at the bottom of all Chinese and English documents under the site https://mosn.io/layotto/ will be changed every time with the update of one document.
What you expected to happen:
Document times without updates should be constant.
How to reproduce it (as minimally and precisely as possible):
For example, the design document has not been updated, but the "last update time of this doc" will always change.
