Refactoring documentation does not work with latest version (0.3.4)

[jenshnielsen]

The example here https://docs.zhinst.com/zhinst-qcodes/en/latest/refactoring/index.html seems out of date since

from zhinst.qcodes import Session

results in an ImportError.

I guess the code should read

from zhinst.qcodes import ZISession

Yes you are absolutely right. We will update the documentation accordingly.
