Fix invalid background-image file name

This is a follow-up of rust-lang#101702.

Apparently the image hash was the wrong one. You can see the error in https://doc.rust-lang.org/nightly/core/primitive.u16.html?search=hello too.

I really need to check if I can adds check for resources load errors in `browser-ui-test`.
