[iOS] fast/mediasession/metadata/artworkdownload.html is a flaky text failure

Reviewed by Anne van Kesteren.

The first promise_test calls internals.loadArtworkImage() which returns a VideoFrame. The
test inspects codedWidth and codedHeight but never calls data.close(). Thus, WebKit emits a
console warning when a VideoFrame is garbage-collected without being closed, which causes a
text mismatch. Per the WebCodecs spec, VideoFrame objects should be explicitly closed to release
underlying media resources.

Files changed (1):
    - artworkdownload.html: Add data.close to explicitly release VideoFrame resources.
