Find out there are some docs formatter that will fail our CI,
due to we merge some wrong PR accidents, such as
https://github.com/apache/dolphinscheduler/pull/12940
This patch asks spotless check run in docs only check to
avoid regression too
Use related path in our docs for imgs, previous
can not use because website need the absolute path
from root directory, and after we merged
apache/dolphinscheduler-website#789 we have covert
function to do that
close: #9426
there are 162 markdown files in dir `docs`
and all file in project is 175 files, so I
think check all file will not add too much
load for our ci, but it could discovered
the dead link in time to avoid some thing
like #9998
