Wikipedia's markup is just terrible for trying to do any sort of scraping or analysis. I once tried to write a script that pulled the latest version of macOS from the sidebar of this article[1] and I gave up because it was difficult and brittle in a way that made it nearly impossible. I'd probably have better results parsing the HTML with a regex. Likewise, I know a friend who literally had to scrap an entire project…
Can't you use their API? https://en.wikipedia.org/api/rest_v1/#!/Page_content/get_pag...
For example https://en.wikipedia.org/w/api.php?action=query&prop=revisio...
returns

I tried it for OSX, and it actually just returns a redirect statement to MacOS. So expect your tool consuming the API to break if you don't handle that in advance.

And then when trying it for MacOS, I can't actually find the version info anywhere in the response data. So you couldn't even get that data without scraping the page.
