Add test for PostgresServerResource.WithInitBindMount

[sebastienros]

Realized it was missing when I extracted MySql which has the same one.

Microsoft Reviewers: Open in CodeFlow

Looks good. Just some minor tweaks.

Would it be useful to assert the contents of the result too?

Test failing with:

And the log has this:

@radical do you know if there is a way to get the Docker logs for the failure? I want to see if there is an issue during the initialization of the image, since we are passing a custom bind mount and the DCP errors seems to indicate that the container hasn't started for this test only.

Worked like a charm, so I know what's happening now:
