Home Blog featured post: image stretches to full row height, not a fixed 220px

The 58%-wide image column at a hardcoded 220px tall produced a badly
elongated crop on wide viewports. sm:h-full lets the grid's natural
row-stretch (driven by the text column) size it instead, matching how
/blog's own featured card already does it.
