Add MDN URLs for chapterInfo features

[chrisdavidmills]

Summary

In mdn/content#34400, I add documentation for the Media Session API MediaMetadata chapterInfo functionality.

I saw that the BCD for these features was already added, but there were no MDN URLs. This PR adds the missing MDN URLs.

One small point — the spec URLs look correct, but in the local page previews, the "No specification found" box pops up. I'm not sure what the problem is.

Thanks Chris, this work will soon be automated away for you by yours truly: #23431 Less things to worry about :)

Looks good here https://pr34400.content.dev.mdn.mozit.cloud/en-US/docs/Web/API/ChapterInformation/artwork, so maybe you need to update your local packages as the data comes from the web-specs package.
