Add song preview player to "submitted beatmap" contest thumbnails

[cl8n]

I'd also want the thumbnails to play the song preview to be consistent with beatmap and featured artist listing behavior.

depends on the main issue of #10673 being resolved, or else nothing links to the actual map anymore. I'm opening a separate issue for this because it seems slightly more involved and isn't addressed by the PR open for that issue

There is a TrackPreview that renders based on the entry option. Just need to render the TrackPreview with a cover image url instead of the icon that links to the beatmap once the main issue #10673 is resolved
