ProjectResource does not support ContainerImageTag MSBuild property

When a .NET csproj overrides the `ContainerImageTag` property, for example like this:

```xml


mytag2


```

We are not respecting the tag in Aspire. For example in this code:

https://github.com/dotnet/aspire/blob/3f36c1365c915a9890d7a47d68616cb8b6ae4b8e/src/Aspire.Hosting.Azure/AzureEnvironmentResourceHelpers.cs#L82-L104

This assumes the image tag will always be `latest` because it sets `localImageName` to just the resource name.

The same problem exists for the `ContainerRepository` MSBuild property. We should be respecting that.

When I set my image tag as above and try to deploy it, I get an error like this:

```

Instead, we should be querying for the ContainerRepository and ContainerImageTag MSBuild properties using something like

```dotnetcli
dotnet msbuild -getproperty:ContainerRepository -getproperty:ContainerImageTag -target ComputeContainerConfig
```

This will return the correct values. Then we should set that information on an Annotation so we can use it whenever we need to get the image name and tag.
