Add container view to container apps

[motm32]

Part of #426

Bringing this branch back from the dead 🧟

Here is how the view looks:

At the moment we are only supporting displaying the information. In the future we hope to add support for adding/uploading environment variables.

I also extended RevisionDraftDescendantBase instead of ContainerAppsItem so when we add further support it already basically has drafts/revisions support. Let me know if we want to change it to ContainerAppsItem instead.

This is looking really nice 😎, can't wait to try it out later

This is how it looks in the case of multiple containers:

I did a quick test in multiple revisions mode and the container items and children still throw errors if expanded at the same time. I think you'll need to add a parent resource ID at the top level to ensure uniqueness. Here's one way to do it:

1. ContainersItem
   a. From: ${containerApp.id}/containers
   b. To: ${this.parentResource.id}/containers

For resolving this.parentResource.id, refer to the implementation in ScaleRuleItem as an example.

2. ContainerItem
   a. From: containerItem-${this.container.name}-${this.revision.name}
   b. To: parentId + /${container.id}

Where parentId is the ContainersItem id.

3. EnvironmentVariablesItem
   a. From: ${this.containerId}/environmentVariables
   b. To: parentId + /environmentVariables

Where parentId is either the ContainersItem or ContainerItem id.

4. EnvironmentVariableItem
   a. From: ${this.containerId}/environmentVariables/${this.envVariable.name}
   b. To: parentId + /${this.envVariable.name}

Where parentId is the EnvironmentVariablesItem id.

5. ImageItem
   a. From: ${this.containerId}/image
   b. To: parentId + /image

Where parentId is either the ContainersItem or ContainerItem id.

6. containerImageNameItem and containerImageRegistryItem
   Add id: ${this.id}/imageName and ${this.id}/imageRegistry, respectively.

Where this.id refers to the parent id, i.e. the parent ImageItem id.
