noto-fonts-cjk: add 70-noto-fonts-cjk.conf
https://github.com/void-linux/void-packages/pull/27468

Description:
Installs a configuration file to config.avail which sets the default font for Chinese, Japanese, and Korean to their corresponding Noto CJK variant. Would be useful for setting up Noto CJK as the default font for CJK languages.
