Subject: [PATCH] fix: HTML artifact preview renders blank in preview mode
 (#876)

The condition guarding ArtifactFilePreview only allowed markdown files
through, which prevented HTML files from reaching the preview component.
Added `language === "html"` to the condition so HTML artifacts render
correctly in preview mode.

Fixes #873
