Update Readme.fonts about Kana

Update to language_it.h

I think that that sentence has been completed its part. 
Because Kana fonts were revised by me the other day(PR #3289), who am a native Japanese.

I'd like to take this opportunity to express one's heartfelt gratitude as a far eastern person,
about you has been maintaining the resource of Japanese despite you are a far western person.
