add news for 2025-04-26

We released [mkiocccentry toolkit](https://github.com/ioccc-src/mkiocccentry) **version 2.4.6 2025-04-26**.

While you are **NOT** required to use this release in order to submit to **IOCCC28**,
we do **RECOMMEND** that you **install and use** it, because among other things, it provides:

* Enhanced the scanning process of topdir, excluding ignored files and directories from the count against the maximum allowed limit.
* Clarified the purpose of a submission title to emphasize that it should not contain names.
* Default handles may now contain UPPERCASE letters.
