DOC: Menu on docs website uninteractable on mobile.

[JHonaker]

Issue with current documentation:

On any page on the main PyMC.io docs site, the main header and hamburger menu are non-responsive on mobile (Safari on iOS, iPhone 15 Plus Max). This makes it impossible to navigate the site through anything but intra-text hyperlinks and search engine results. It’s been this way for at least a month. Probably longer, but I’ve only been actively trying to peruse the examples on my phone in the evenings since I set up a new project at work.

I attempted to find another reference to this problem on the Issues, but I was unable to find any other reports.

Idea or request for content:
