feat(policy-summary): add spec to structured view

[schogges]

This is the first part and in a follow-up I'll add more view types for the config. Here I added the spec in a code block to the structured view, so the user can still get all information in this view and doesn't need to switch to YAML.

I added a prop to hide the Copy as K8s button from the code block. I think the spec is agnostic to universal and k8s.

Still looking at this but just spotted something.

Totally not related to this PR, but this looks like it could be a pre-existing bug to me? wdyt?

I'm not totally sure what logic it uses to make the targetRef say [Mesh] instead of [MeshService]?

Looks good to me! I had one tiny suggestion, and a non-important curiosity question. Otherwise I reckon this is good to go! lmk on those

Oh wait, I think this depends on a topLevel targetRef, so I think the screengrab I posted here is correct?

We fall back to Mesh in case spec.targetRef is not set 🤔
