This is a thing the image grid editing page on the staff site lets you do; not sure if it does everything we want to yet, should check

I thought that making an image grid editor would be the best way to let us create a customizable display showing the sponsors, but then unfortunately I thought better of the grid layout and made a sponsor display component (public-frontend\src\components\sponsors.vue) that shows their logos in a (wrappable) row or column format.

Since it's made out of basic HTML and thus is still easy to edit, it's not the worst thing in the world? But the existing image grid editor on the staff site could honestly be deleted and replaced with a simple editable ordered list of the sponsors, their websites, and the images to display for them, possibly with some extra fancy features like the ability to set some of them to be bigger than others.

I removed the image grid editor, but have not added a sponsor data editor yet
