Fixing typos in the Kawa website

[Duncan Mak]

Hello Per,

We were talking on #scheme today, and while discussing Kawa's support for
SAM conversion, someone saw that there's a typo:

<daviid> duncanm: it seems there is a tipo in the manual "Such a class is
sometypes called a SAM-type ..." instead of "sometimes called ..." I guess

This typo should be fixed - also, is the text to the website available for
others to change up? If it's possible to fix the typo via  PR, I'd be glad
to do it myself.
