docs/zh_CN: add back the missing part in the English version
The zh_CN kasan document misses the code change in commit eefe68280c94
("kasan: Add documentation for CONFIG_KASAN_EXTRA_INFO").
Fix this by adding the translation of the missing part.
Note that this missing commit is found by checktransupdate.py
