Using .AddDockerfile() forces the resource name to be lowercase

Describe the bug

All of the resources in my Aspire project have names that are using PascalCase. I tried adding a new resource that is built from a Dockerfile, but I'm getting the error invalid tag "MyResourceName-image-b3a94344fc439fed1ba4f80c352c4fb0417a6162:latest": repository name must be lowercase.

This happens because the WithDockerfile() extension is using the name of the resource to generate the name of the docker image, but it does not provide a way to separate the naming of the image from the name of the resource.

Expected Behavior

The AddDockerfile() and WithDockerfile() extensions should provide an overload that allows users to influence the naming of the image so that it does not have to be tied to the naming of the Resource.

Steps To Reproduce

var builder = DistributedApplication.CreateBuilder(args);

builder.AddDockerfile("MyResourceName", ".");

builder.Build().Run();

Exceptions (if any)

invalid tag "MyResourceName-image-b3a94344fc439fed1ba4f80c352c4fb0417a6162:latest": repository name must be lowercase
