bug#47480: logo gprolog: hash mismatch

[phodina via Bug reports for GNU Guix]

Hi,

I've looked at the package gprolog and it was updated by Efraim Flashner in 
commit
1914d24b452ca6dad30fad6f1faa5f611fa740b0 to version 1.5.0.

There's a note saying "Recent versions are not hosted on the GNU mirrors".
