Describe the bug

When creating a eg. Postgres database container the random port mapping does not work.

To Reproduce
Steps to reproduce the behavior:

  await new TestcontainersBuilder<PostgreSqlTestcontainer>()
    .WithDatabase(
    new PostgreSqlTestcontainerConfiguration
    {
      Database = "test",
      Username = "user",
      Password = "password"
     })
     .Build()
     .StartAsync();

exposes some random port eg. 49132, but the actual port I can see in docker is different.
If I explicitly map the port it works.

Desktop (please complete the following information):

• Version 3.3.3 with WSL2
