CRW upgrade instructions (currently: https://access.redhat.com/documentation/en-us/red_hat_codeready_workspaces/2.1/html/installation_guide/upgrading-codeready-workspaces_crw) need to be modified:

• New instructions for OperatorHub-based upgrade from 2.0 to 2.x
• Link to 2.0 docs for those who still need to upgrade from 1.2 to 2.x
