Env check

[bnmajor]

Adds an environment check notebook that is designed to check the environment that the user is running in to make sure that all required dependencies and extensions are correctly installed. Ideally run first before any other notebooks to prevent common issues around dependencies and extension loading.

@thewtex It looks like Python 3.11 is failing with the following:

ImportError: Wasmer is not available on this system

It does seem that there are no wheels for Wasmer for 3.11: https://pypi.org/project/wasmer/1.1.0/#files, but running the tests locally in a conda env with 3.11 I am not seeing this error. I am running Ubuntu 20.04 still but ubuntu-latest has been on 22.04 since October so that shouldn't be the issue I don't think? Any ideas?

[thewtex]

@bnmajor yes, I ran into this, too, filed an issue: wasmerio/wasmer-python#696

For now, let's disable 3.11 in CI, create an issue to re-enable. I will likely use an alternative to wasmer-python itk-wasm.

[bnmajor]

@thewtex Sounds good, thanks! #618 disables 3.11 testing for now

[bnmajor]

@thewtex This should be good to go now

[thewtex]

To avoid the impression that all the dependencies fetched here are required for itkwidgets, can please clarify here:

required dependencies -> example notebook dependencies

other notebooks -> example notebooks
