Fix import in notebook example

[lognaturel]

Thank you, @Thaliehln!

This specific one is a typo I've made more than once. For better or for worse, both do work so it's likely we'll see both pop up. I think it would be ideal for only pyodk.client to work so examples are consistent but I'm not sure how to achieve that.

EDIT: now I see from @Thaliehln's note that it did /not/ work. What platform are you on, @Thaliehln? I'm wondering whether the behavior I get is related to how macOS treats case for filenames. Regardless, we should be consistent in examples.

Hi @lognaturel, I am on Microsoft Windows (10.0.18362.1679). I am running Python in Conda environments (conda 4.10.3), including Python 3.8.13 and Python 3.9.7.
If your MacOS is not a case sensitive file system this could indeed explain why the import statement works smoothly on your side while it raises an error on mine (as I have never really used Mac, I am not aware of the specificity of MacOS vs. Windows or Unix).
I agree with you that it is important to have consistent examples, also so that those who are just starting with Python are not stuck at the import step and can start playing with the pyODK package
