UseOnline property doesnt work with GCC high instances

[imranakram]

Hello @MscrmTools

I got this issue reported in PRT pointing that the UseOnline property doesn't work for GCC high instances. This is ofcourse an edge case but I think it could be solved at this moment by checking the major version to be 9.2 since currently the latest onprem is at 9.1.

        /// <summary>
        /// Get or set flag to know if we use CRM Online
        /// </summary>
        [XmlIgnore]
        [Browsable(false)]
        public bool UseOnline => OriginalUrl.IndexOf(".dynamics.com", StringComparison.InvariantCultureIgnoreCase) > 0;
