WithBindMount: create source directory (podman)

[tmds]

One distinction between podman and docker for bind mounts is that docker will create the specified path if it does not exist while podman will fail if it does not exist.

It would be nice if the Aspire orchestrator would create the directory when the orchestrator is podman so this difference doesn't bubble up and requires the user to handle it in the AppHost.

@karolz-ms Where do you think this logic should go?

[karolz-ms]

I agree with @tmds, having this logic in the orchestrator makes sense

This is fixed in the 0.4.0 version of DCP
