chore: update Kubernetes resources to v1 API for provider v3 compatibility (#616)

## Description

As part of
https://registry.terraform.io/providers/hashicorp/kubernetes/latest/docs/guides/v3-upgrade-guide
various resources change from non versioned to versioned. This PR
changes the Coder authored templates to versioned resources.

- Updated kubernetes_persistent_volume_claim to
kubernetes_persistent_volume_claim_v1
- Updated kubernetes_deployment to kubernetes_deployment_v1
- Updated kubernetes_pod to kubernetes_pod_v1
- Updated kubernetes_secret to kubernetes_secret_v1
- Updated all resource references and dependencies

I also had to fix up a couple of templates, i.e. remove `agent_name` as
it wasn't valid usage, `agent_id` remains. The `source` parameter for
jetbrains module in
[registry/coder/templates/kubernetes-envbox/main.tf](https://github.com/coder/registry/pull/616/changes#diff-83996ad9def3fae3b69981faee7d682964acc8716a4d04edfd7c4374f0a1d15c)
also had to be fixed.
