[Feature]: Allow access to the configuration builder in DistributedApplicationTestingBuilder.CreateAsync in TUnit.Aspire

[redoz]

Problem Statement

I'm trying to get access to the to the configureBuilder param in DistributedApplicationTestingBuilder.CreateAsync used here
It seems like maybe it could be handled the same way as AppFixture.Args?
If you're willing to take a PR let me know, I should have some time this weekend.

Thanks for all the effort you've put into TUnit, it's working out fantastically for our use-case.

Proposed Solution

Add a protected virtual to AppFixture similar to protected virtual string[] Args => []; something like:
protected virtual Action<DistributedApplicationOptions,HostApplicationBuilderSettings> ConfigureCallback => static (_, _) => return; and pass it to DistributedApplicationTestingBuilder.CreateAsync

Alternatives Considered

I did some poking around but I didn't see another way of getting access other than through the CreateAsync function. You could copy/paste the whole InitializeAsync but that could cause hard to find issues if the internal implementation changes since it wouldn't be called anymore.
