Bug 1860883 [wpt PR 42730] - Add noto fonts to the Docker image, a=testonly

Automatic update from web-platform-tests
Add noto fonts to the Docker image

This ensures that we have fallback glyphs for most/all
characters. This affects some tests
e.g. css/css-fonts/size-adjust-unicode-range-system-fallback.html (see
https://bugzilla.mozilla.org/show_bug.cgi?id=1860124)

Covering all of unicode does mean that we end up with a rather large
increase in the docker image size. If this causes problems we could
just install fonts-noto-cjk to fix the known breakage.
