Are there other tests we could remove, e.g. scikit-bio's?

Yes, but they're not that big - I figured simplicity wins over chipping away more tiny pieces 🤷

Can you confirm with @clausmith @lynchde on the wheel-only change?

I wonder why we had this as a dependency

I vaguely remember at one point the main container uploading the ipynb file. It's now done in a sidecar that has a different image with awscli.

This PR trims down the size of the docker image from ~3.8GB to ~1.2GB. Out of the remaining size, >1GB are the Python packages that we probably want to keep around.
The image could be further trimmed a bit but not without consequence (e.g. slower package loading on start). Let's only get to that if we deem it necessary.
Note: this PR removes the compilers and their tooling (~600MB) from the image so only Python packages with wheels can be installed, if a package requires compilation, it will fail the
pip install.
