How to file a helpful issue

Brief summary

1. The Qubes website was using jquery-2.2.2.min.js.
2. GitHub's automated "Dependabot" created this alert: Potential XSS vulnerability in jQuery.
3. In an attempt to fix it, I upgraded to jquery-3.6.4.min.js (QubesOS/qubesos.github.io@b494ccd).
4. However, this broke the hamburger menu (the menu that replaces the nav bar on small screens).
5. So I reverted my commit, and the website is back to using jquery-2.2.2.min.js (QubesOS/qubesos.github.io@9a710a0).

Unfortunately, I'm not a professional web developer and don't really know how to fix the hamburger menu so that it's compatible with newer, non-vulnerable version of jQuery. I also don't know how serious this vuln is for us in our specific use case. Our site is mostly static and doesn't handle any sensitive user data. We also have this explicit warning: FAQ: Should I trust this website? Nonetheless, if it presents a significant risk for users, I'd rather let the hamburger menu be temporarily broken until someone with the requisite expertise can fix it.
