"CET" is not a valid timezone all year around. "Europe/Stockholm" is.
This newer version has ready-built wheel packages for Python 3.10, so we won't need to have gcc installed in our production runner image.

In the `master` branch currently, the image is around 1.2 GB, while this
build clocks in at 300MB. See details below:
