[ruby/psych] Add quotes to the strings "y" and "n"
'y' and 'n' are kind of ambiguous. Syck treated y and n literals in YAML documents as strings. But this is not what the YAML 1.1 spec says. YAML 1.1 says they should be treated as booleans. When we're dumping documents, we know it's a string, so adding quotes will eliminate the "ambiguity" in the emitted document Fixes #443 https://github.com/ruby/psych/commit/6a1c30634e
