Move "hide banner" button into a landmark region

[coseeian]

The "hide banner" button was previously not contained within any landmark region, which could hinder navigation for screen reader users. To address this accessibility issue, the button has been moved into a

landmark region. This change ensures that all interactive elements are contained within appropriate HTML5 landmarks, improving both accessibility and navigability.

I'm sorry it's taken me a while to get to this!

When I test this, I find that the design no longer works. Instead of being fixed to the bottom of the screen, it is part of the footer in a way not intended by the design.

It is it possible to include it in an adequate landmark but make sure that it is available on the site as intended in the design, or, to be honest, I think it would be alright to remove the banner completely.

It has limited discoverability in general, and is not too useful to draw attention. So it if is also an accessibility issue, I don't think there is a strong argument to keep it. cc @davepagurek does that sound reasonable? To stop using the banner entirely and rather focus on the navigability of the other links on the site?

This is the thing along the bottom of the page right? Currently we rely on that when the Processing Foundation is seeking donations and when we have other events, do we have an alternative spot in mind for those? Maybe an additional section on the home page?
