[FR] Support fetching the Advanced API Risk Assesment Score

[psaini0212]

Is your feature request related to a problem? Please describe.
We are keen to enable the Advanced Apigee API Security in our Apigee ORG; one of the feature is risk assessment of the API; where it provides the severity and risk assessment score. We would like apigeecli to support that to fetch that information for a deployed proxy in an env

Describe the solution you'd like
The idea is to integrate the risk assessment functionality into our pipeline—specifically, we want to programmatically retrieve the severity/score in lower environments and use it as a guardrail to control deployments into higher environments.

Describe alternatives you've considered
The alternative here is to build our own custom solution using the REST API available; while this is feasible but then we are already using apigee cli in our pipelines so having the capability there will help a lot
