Ruby

After this commit: https://github.com/ruby/ruby/commit/9be3295d53b6fd9f8a3ad8157aa0655b1976d8ac -- RDoc loses documentation attahed to OpenStruct class, see https://docs.ruby-lang.org/en/master/OpenStruct.html, which currently looks this way:

class OpenStruct
<here shoud be explanations>
Public Class Methods

require should be put above docs.

I'd provide PR myself, but I kinda lost between core repository and https://github.com/ruby/ostruct (which seems outdated)?..
