I don't think you can update the code that is actually going on at http://www.wikipedia.org but you could always take an open-source wiki software already out there and customize it to add in the functionality you would like.
You'd contribute to MediaWiki. However, I strongly suspect you won't get features like polls accepted into the codebase (or at least not adopted by Wikipedia). I suspect that a feature like that would already have been implemented if enough folks on Wikipedia wanted it.

我相信您指的是为 MediaWiki 创建插件。
I believe you're referring to creating a plugin for MediaWiki.
我认为您无法更新 http://www.wikipedia.org 但您始终可以使用已有的开源 wiki 软件并对其进行自定义以添加您想要的功能。

您可以为 MediaWiki 做出贡献。 但是，我强烈怀疑您不会获得代码库接受的民意调查等功能（或者至少不会被维基百科采用）。 我怀疑如果维基百科上有足够多的人想要的话，这样的功能早就已经实现了。
