Subject: kasan: delete CONFIG_KASAN_MODULE_TEST
Date: Mon, 14 Oct 2024 07:57:01 +0500

Since we've migrated all tests to the KUnit framework, we can delete
CONFIG_KASAN_MODULE_TEST and mentioning of it in the documentation as
well.

I've used the online translator to modify the non-English documentation.
