Remove unreferenced images

Discovered by my new automation.

To review this, you probably need to search through the entire content to confirm that these files are not referenced anywhere.

I did this and didn't find them referenced via relative links in en-US. The problem is that these are used in translated-content:

../translated-content/files/ja/web/api/window/confirm/index.md:![Firefox の confirm](firefox_confirm_dialog.png)
../translated-content/files/ru/web/api/window/confirm/index.md:![firefox confirm](firefox_confirm_dialog.png)
../translated-content/files/zh-cn/web/api/window/confirm/index.md:![Firefox 确认对话框](firefox_confirm_dialog.png)
../translated-content/files/pt-br/web/api/window/confirm/index.md:![firefox confirm](firefox_confirm_dialog.png)
../translated-content/files/ko/web/api/window/confirm/index.md:![firefox confirm](firefox_confirm_dialog.png)
../translated-content/files/es/web/api/window/confirm/index.md:![Firefox confirm](firefox_confirm_dialog.png)
// etc.

There are only a few that are unused in all locales, as far as I see:

playcanvas-github.png
shapes-playcanvas.png
flexbox-example6.png

I think safely removing the others is blocked on doc updates in the translated content repo or the images will break, as far as I understand.

I'm not sure about that because my own habit is to remove images whenever they are unused in our content—I'm fairly sure some others do that too. I think it's a bit of a hassle to have to care about translated content when maintaining the main content, and any out-of-sync should be a bug in itself, even without a broken image, so I'd argue that those pages are already broken as-is. This PR just performs cleanup that ought to have happened with the content change.

@mdn/localization-team-leads FYI there is some cleanup incoming here - could you please take a look at the removals and try to plan for these deletions so you don't have broken images in downstream pages?

I understand, yes. Basically, I'm +1 on the changes, but I'd like to give the translated content teams some time to react before we remove them, how does that sound?

[Josh-Cena]

Yeah sure.
