Bug#948700: scikit-learn: re-enable build and installation of -doc package

[Sandro Tosi]

Source: scikit-learn
Version: 0.22.1+dfsg-1
Severity: important

Hello,
in order to package 0.22.1, we had to disable the build of the documentation via
sphinx, as that's requires sphinx 2.* while debian currently only ships 1.8.5

Refer to:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=944913
https://github.com/scikit-learn/scikit-learn/issues/16087#issuecomment-573092993

Please re-enable as soon as #944913 is addressed.

Regards,
Sandro
