Make sidebars either collapsible, or make them flow above/below page content on lower breakpoints.

Is your feature request related to a problem? Please describe.

When I add a sidebar to a page, and I view the page on mobile, the sidebar takes up much of the available width.

Describe the solution you'd like

On mobile breakpoints, it would be nice if the sidebar either showed up inline, between the breadcrumb/action box and the page content, or below the page content. Alternatively, making it collapsible like the filters sidebar on index (but perhaps open by default) would be a good option.

I'm currently transitioning my org from ActiveAdmin to Avo, so this isn't really a priority for us anymore. That said, I imagine it would be quite useful to people who continue to be invested in ActiveAdmin.

I wanted to comment on the current(CSS-only) implementation of the collapsible sidebar,
it is currently impossible to show it without using mouse/trackpad and clicking on it, so accessibility hurts a bit

if it was a button tag instead, then it can be triggered without any issues.
If I'll find a simple way to fix it, I'll open a PR
