Previously, the Getting Started guide only contained instructions for installing RHDH via Helm on RHOCP. Rather than add Operator instructions to the Getting Started guide, instructions for installing RHDH on RHOCP via Helm and Operator are now contained in the Admin guide only. The Getting Started guide now provides new conceptual information about RHDH installation and directs the user to the Admin guide for complete RHDH installation instructions via a link. 

Please review the PR, which resolves 4 installation-related docs issues, including RHIDP-1747.
