The error is a 302 error, and I just tested the link, and it's fine. It's an edit page link. I wonder if we should just drop htmlproofer and stick to lychee everywhere?

The problem is that sometimes, the action doesn't return the actual issue in the action output. this means we have to look at the raw logs, which are annoying 😆 And it's likely failing because of hitting the same link over and over like an edit page link is on every single page!

maybe there is another accessibility check tool that we can use and then lychee for links, which I think you've set up in other repos with some success?! in the meantime let's see if reruning the action returns a green check. I think we can merge this regardless of whether it does or not!
