Small Typo of Weather.scala in Japanese version doc

[kirinsannnnnnnnnn]

// in markdown in source is displayed as / on website in browser, therefore core/src/main/scala/example/core/Weather.scala will be fail.

English version is escaping the character correctly.

I would appreciate it if you fix it when you have a time.

Looks like the English version was fixed in #767
