Fix: Put last SVN revision back in NewGRF version number (#6843)

This is necessary to be compatible with some Game Scripts that might trigger compatibility modes if the SVN revision part is wrong. Potentially some NewGRFs might also be affected.

See for example [SuperLib's Helper class](https://dev.openttdcoop.org/projects/superlib/repository/entry/helper.nut#L280), containing this function:

    function _SuperLib_Helper::HasWorldGenBug()
    {
    	local version = _SuperLib_Helper.GetOpenTTDVersion();

    	if (version.Major == 0 || (version.Major == 1 && version.Minor <= 3)) {
    		return version.Revision < 25339;
    	} else {
    		return version.Revision < 25305;
    	}
    }

If this function sees a Revision value of zero, it might trigger a workaround not required, causing a regression in scripts dependent on this. The MinimalGS example, for one, will trigger this.
