Mikhail Korobov 955473f475 Docs: unescape regexes in Pattern Tokenizer docs
Currently regexes in Pattern Tokenizer docs are escaped (it seems according to Java rules). I think it is better not to escape them because JSON escaping should be automatic in client libraries, and string escaping depends on a client language used. The default pattern is `\W+`, not `\\W+`.

Closes #6615
