fix doctest errors in sudoku puzzle tutorial

[Fe-r-oz]

Based on the output on GitHub actions, the are a few doctests errors left. It seems that for Script examples, using # output is necessary to display the output and using ; does not suppress output. I used ; to suppress the output and then # output which displayed the output which causes doctests errors.

Apologies for the inconvenience. Hopefully, this will reduce the number of doctests errors.

TODO: Use CI Documentation to detect these doctests/documentation errors when the CI runs after submitting a PR.

honestly I am always having doctest errors...doctest seems to be too sensitive. Sometimes when I run the docs on my own computer (docs/make.jl) and it works, it has errors in github actions.

Thank you for contributing these examples...you seem very interested in this package, if you message me on linkedin we can discuss it (I tried but could not send a connection request)

Thank you for the reminder! Yeah, that would be great. Apologies for the inconvenience, I think it was due to connection request settings that we couldn't connect earlier.
