AEMaaCS version information: being able to determine current version, latest version and being able to upgrade envrionments (dev) though CLI

[#1]

Request for Feature Enhancement (RFE) Summary:	At the time of writing AEMaaCS environment API [1] does not allow me to: inspect which version of AEMaaCS given environment runs check if the version I have is the latest upgrade the environment programmatically. The only way to do it is via Cloud Manager Web UI (non PROD envs) or support ticket (STAGE/PROD). The latter may not be something Adobe considers doable (due to RO/RV), but we'd love to see such a feature for lower level environments. We has dozens of dev environments spread across multiple programs, so it is cumbersome to keep them in sync [1] https://developer.adobe.com/experience-cloud/cloud-manager/reference/api/#tag/Environments
Use-case:	enable to "automate upgrades" and across many  programs and environments (customers with up to 10 programs) - and to understand current and latest available verison.
Current/Experienced Behavior:	API and CLI do not provide information on  * current AEM version of environment * latest available version provided for the environment * ability to execute upgrade though API/CLI
Improved/Expected Behavior:	API and CLI should offer the option to request * current AEM version of environment * latest available version provided for the environment *  execution of an upgrade (add upgrade flag and execute full-stack-pieline)
