Just checked. Still needs it. I don't have Rosetta installed and I don't want to install Rosetta just to be able to use a game controller with DuckStation or Aethersx2. When I can also connect a PS4 controller and not need any of that.
You have an old Steam.app stub, download the latest one and rosetta will not be necessary.
If you had rosetta it would be able to self-update to the new universal binary, without it you have to do this one update manually.
I downloaded from here and I instantly get a pop-up about requiring Rosetta.

Odd if true. It's clearly a universal binary, not sure what's going wrong for you.
