ABI generation broken for Ricardian contracts in 1.8

[aclark-b1]

Summary from Telegram:
Does anyone know how to include ricardian contracts for actions in eosio-cpp v1.8.0? The old way of doing this entailed creating a markup file with the name .contracts.md in the same folder as the cpp file and it would automatically add the contents into the abi. Has something changed?

Getting warning: abigen warning for all actions

Saving RC files in root or ./ricardian folder using .contracts.md
