[PATCH 3/3] Reword note on missing CJK fonts

[Akira Yokosawa <akiyks@gmail.com>]

Use past tense as the fonts can be installed after the fact.
Add suggestion to install "Noto Sans CJK" and "Noto Serif CJK"
font families. ("Noto Serif CJK" is optional.)

This note won't be seen by many, but feedback from a native
speaker would be much appreciated.

To see this note, you need a system without the "Noto Sans CJK"
font.  (Not expecting you'd actually do it.)

    Thanks, Akira
