PMM Demo server as primary action on portal page

Problem: current Portal page is about PMM demo but the Primary action (purple button) is about K8s. So the user can't even see the PMM in this case

An additional problem  - While being logged in the portal and have "connected PMM " I still asked to login to my PMM 

Possible solution: 

1. replace Primary action from "Copy Kubeconfig"  (keep it as link, like  view kubeconfig ) to "Access PMM". To increase visibility of the button. 

2. replace the link for Accessing pmm  from 
   https://pmm-demo-XXXpercona.systems/ 

to  

https://pmm-demo-XXXpercona.systems/graph/login/generic_oauth 
 (This will get user logged in inside PMM automatically)
