Error message

SUMMARY
Trying to use the 'Check for new version' option in the help menu fails because it can't find the sha256 file on the server.
It appears that the files have been renamed '.sig', so can be fixed by copying these files to also have a '.sha256' suffix

STEPS TO REPRODUCE
1. In version 8.1.0, click 'Help'
2. Click 'Check for new version'
3. In @nd dialogue box that opens, click 'Download'

OBSERVED RESULT
Error message : File not found error for digiKam-8.6.0-Win64.exe.sha256

EXPECTED RESULT
Download and install new version

SOFTWARE/OS VERSIONS
Windows: 10
macOS: 
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: 
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
The whole point of this option is to make life easy for newbies, it needs to be fixed by including an sha256 file in the directory so that the action will complete, not by telling people to download a newer, 'fixed' version.
