CI win make bundle: remove unused commands

Remove commands that actually do nothing because uv-qt.exe is installed
by make install and the contents of bin/ subdirectory is not copied
"as is" as the command seem to imply.

+ use $(TARGET) in Makefile instead of bin/uv (which will be bin/uv.exe
in MSW but obviously it worked even without the extension)
