Current README setup does not work on Ubuntu 20.04.3 LTS

[RicoFio]

Currently, Ubuntu users cannot simply docker run following the suggested setup in the main readme.
Common error messages were:

rico@laptop$ sudo docker run -p 8888:8888 -v $(pwd):/home/jovyan/work  mtasnim/jupyter-pyspark-duckdb
WARNING: The requested image's platform (linux/arm64) does not match the detected host platform (linux/amd64) and no specific platform was requested
standard_init_linux.go:228: exec user process caused: exec format error

and

rico@laptop$ sudo docker run --platform linux/arm64 -p 8888:8888 -v $(pwd):/home/jovyan/work -e JUPYTER_ENABLE_LAB=yes mtasnim/jupyter-pyspark-duckdb
standard_init_linux.go:228: exec user process caused: exec format error

(The errors happen in both cases with or without sudo - using sudo was our "last resort")
To overcome issues we had to run the following in our terminals to install the required underlying virtualization software

rico@laptop$ docker run --rm --privileged multiarch/qemu-user-static:register  # Not sure this is necessary
rico@laptop$ sudo apt-get install qemu binfmt-support qemu-user-static

It is weird that we require to install this locally, but we assume that these are some hardware virtualization libraries which cannot be brought in to docker.

After the above steps are taken, the remaining commands of the setup should work out of the box.

Thanks @keerthybalan for finding this!

Thank you for posting this.
Was stuck and after installing this locally it works!
