Update from to-markdown to turndown

Browse source 
We got a security alert for a regular expression DoS attack on our used
library `to-markdown`.

After checking `to-markdown` to be maintained or not, it turned out they
renamed the library to `turndown`. So upgrading to `turndown` should fix
this vulnerbility.
