I totally agree with you on how ridiculous this is. But it's all about trade offs in the end. In the case of Docker+Wasm you get portability and delivery speed.

You build one image for the wasm32/wasi platform and now it can run on any architecture that has Docker, just like that. And also you don't carry the whole OS baggage of a typical container. Only the language runtime. So download times are faster.

Lastly, the Docker deployment is just the easiest way for a WASM application to reach people. They can try it out without the necessity to setup and support a WASI runtime.
