Adaptable content

1. 🗜Resize Text

Users must be able to resize text, without using assistive technology, up to 200% with no loss of content or functionality - WCAG 1.4.4

### Tasks
- [ ] When you click on the Read The Docs version switcher (the black one on bottom right), the button to close it becomes obscured and the dropdown cannot be closed.

2. 📐Text spacing

Users must be able to adjust text spacing with no loss of content or functionality - WCAG 1.4.12

### Tasks
- [ ] The text visible in the version switcher doesn't pass this test
- [ ] The "Search" & "Ctrl K" text on the search bar doesn't pass this test
- [ ] 	The "Search the docs..." text when you click the search button
- [ ] The "More" label of the "More" dropdown in the header nav

The Read the Docs version switcher might be out of scope for us to fix, but if we have time, we can give it a try. I suspect that a lot of the sites that use PyData Theme might turn on the option for the Read The Docs switcher, so it would be nice if we could get that fixed upstream so that our users downstream won't inadvertently create accessibility issues on their sites by using Read the Docs. Does that sound about right, @trallard?

Will have to investigate the text spacing issue. One thing I noticed is that all of the elements that failed to respond to the Accessibility Insights toggle were <button> elements.
