Extensions: Vue 3 extension validation and compatibility

[aalves08]

Is your feature request related to a problem? Please describe.

Create an independent set of e2e tests that install, do tactical navigation to key areas to test changes like defineComponent and schemaDiet as examples of important steps to cover, and uninstall of extensions to make sure that they are working properly. These e2e tests could run over-night (not in every PR) and should also cover different combinations of extensions + Rancher versions.

Interesting testing scenario: https://github.com/rancher/dashboard/issues/10659 - build extension with a "verdaccio" version of shell, then run a "simple" test spec that installs extension and goes to dashboard screen of each extension. Should capture the case of defineComponent where it was working in 2.9, but it did not work in 2.8 (leverage matrix to achieve this)

Official extensions list:

• [x] Elemental: https://github.com/rancher/elemental-ui (https://github.com/rancher/dashboard/pull/11508)
• [x] Kubewarden: https://github.com/rancher/kubewarden-ui (https://github.com/rancher/dashboard/pull/11668)
• [ ] CAPI 🐢 : https://github.com/rancher/capi-ui-extension
• [x] Neuvector: https://github.com/neuvector/manager-ext (https://github.com/rancher/dashboard/pull/11692)
• [ ] Stackstate : https://github.com/StackVista/rancher-extension-stackstate

Checklist of todos:

• [ ] Have a workflow running with basic spec in 2.10 (there isn't a -head notion for 2.10)
• [x] Have a workflow running with basic spec in 2.9 (https://github.com/rancher/dashboard/pull/11508)
• [ ] Have a workflow running with basic spec in 2.8 (WIP - https://github.com/rancher/dashboard/pull/11545)
• [x] Have the workflow report back to our Slack (https://github.com/rancher/dashboard/pull/11660)
• [ ] Have a workflow with a built shell version for each system

Other topics:

• Workflow can run multiple systems via matrix -> doable, test works, but there's differences in e2e tests in branches to consider...

@aalves08 is this still on track for 2.10.0 or is 2.10.1/2.11.0 more appropriate? I'm still trying to figure out if this is actually in Review or truly in the Backlog.

@gaktive I would say that is now in backlog in light to other priorities. 2.11.0 is the appropriate milestone, imo.
