[DOCS] [MLLIB] Fixing misformatted links in v1.4 MLlib Naive Bayes documentation by removing space and newline characters.

A couple of links in the MLlib Naive Bayes documentation for v1.4 were broken due to the addition of either space or newline characters between the link title and link URL in the markdown doc.  (Interestingly enough, they are rendered correctly in the GitHub viewer, but not when compiled to HTML by Jekyll.)

 Within that context, each observation is a document and each
 feature represents a term whose value is the frequency of the term (in multinomial naive Bayes) or
 a zero or one indicating whether the term was found in the document (in Bernoulli naive Bayes).
