Add Noto Sans JP as a fall back font to support Japanese characters in our packaging guide

This issue is a result of 
https://github.com/pyOpenSci/python-package-guide/issues/504

Where we determined that using NOTO SANS JP as a fall back font in our guide might fix the Japanese character issue. 

We should vendor that font.
[this site](https://gwfh.mranftl.com/fonts/noto-sans-jp?subsets=latin) should help us make the vendoring part easier!
