Subject: [PATCH] Lobsters: Switch from commonmarker to markly

Commonmarker swtiched to Rust via Magnus which is perpetually
incompatible with Ruby HEAD due to baking in the ABI and hardcoding
other Ruby internals.

markly is a maintained fork of commonmarker 0.x, which is not using
deprecated APIs and we can expect to remain compatible with Ruby HEAD.
