[REQUEST] Add journal citation to web page

[PaulWAyers]

While the journal publication is listed in the readme on GitHub, it is not on the web page. It should be added.

Hi maintainers 👋
I’m Lipika (WoC applicant). I noticed this issue is assigned already, but I’d be happy to help by submitting a quick PR adding the missing journal citation to the web page/docs if you’d like.
Please let me know if I should proceed and where the website source lives (docs/website repo). Thanks!
