mlir-opt vs mlir-translate ?

In the line referenced [1] , why do you use mlir-translate instead of mlir-opt ?
Background here (https://discourse.llvm.org/t/doc-mlir-translate-mlir-opt/60751)

I would try to make it mlir-opt in case it's a bug, as mlir-opt is similar to llvm-opt and is what used for testing the IR, which can be the main usage of CE.

Review bin/yaml/cpp.yaml at the referenced line and compare the roles of mlir-translate and mlir-opt using the linked Discourse discussion. Confirm which command Compiler Explorer should use for this MLIR case; done means the configuration uses the appropriate command or the issue has a documented rationale for keeping the current one.
