Release [windows] build of Slicer fails with error on sphinx-build

Hello Team,
Kindly wanted your help on the below build issue:


Sphinx build is just a warning. It is expected if you haven’t set up sphinx. You can ignore it.

To learn more about the build error, you need to look a the build log. The error list does not contain information about the root cause of the error (I usually search for the first occurrence of : err).
