fix(homepage): move minecraft widget from top bar to its service tile

The minecraft widget type isn't a valid top-of-page info widget (only
resources/datetime/search/etc. are), so homepage rendered a "Missing
minecraft" placeholder there. gethomepage.dev only supports it as a
per-service widget, so attach it to a new Minecraft tile in the
Gaming group instead.
