@zpi1223 need to fix docs check for kerberos translation file.

I don't know if you mean this check error below：
"
ERROR:mkdocs.structure.pages:File not found: operations/external-authenticators/kerberos.md
ERROR:mkdocs.commands.build:Error reading page 'operations/external-authenticators/kerberos.md': [Errno 36] File name too long: '/place/sandbox-data/tasks/3/8/1108249483/ClickHouse/docs/zh/operations/external-authenticators/kerberos.md'
"
However, what I have learned is the existing directory structure, and I just make a supplement for the internal kerberos.md content.
The directory structure is the same for en/zh/ru/ja module.
I wonder if you have any good suggestions .

@zpi1223 it seems that these files are creates as symbolic links. Just create them as ordinary .md files.
