Describe the bug

Run the engine with a demo version of the game, open any map and try to view Puzzle. You will hit the following assertion:

fheroes2/agg/agg_image.cpp:509: void {anonymous}::drawImageOnButton(const fheroes2::Image&, int32_t, int32_t, fheroes2::Image&, fheroes2::Image&): Assertion `!image.empty() && !releasedSprite.empty() && !pressedSprite.empty()' failed.

This is a regression code introduced in #10241:

case ICN::VIEWPUZL:
        case ICN::EVIWPUZL: {
            if ( _icnVsSprite[id].size() == 1 ) {
                auto & original = _icnVsSprite[id][0];

                // The original puzzle image has a rendered button. We should remove it.
                const auto & streamsImage = fheroes2::AGG::GetICN( ICN::EDITPANL, 3 ); <--- THIS IS WRONG!
                fheroes2::Sprite croppedImage = fheroes2::Crop( streamsImage, 0, streamsImage.height() - 48, streamsImage.width(), 48 );
                if ( id == ICN::EVIWPUZL ) {
                    fheroes2::ApplyPalette( croppedImage, PAL::GetPalette( PAL::PaletteType::GOOD_TO_EVIL_INTERFACE ) );
                }

                fheroes2::Copy( croppedImage, 0, 8, original, 0, original.height() - 40, original.width(), 40 );

                fheroes2::CreateDitheringTransition( croppedImage, 0, 0, original, 0, original.height() - 48, original.width(), 8, false, false );
            }
            break;
        }

This issue must be fixed for the upcoming release.
