Minimal Example Fails to Start

Thank you for providing this useful testcontainers module.

I noticed that a minimal example fails because no default startup command is set:

    keycloakContainer, err := keycloaktc.RunContainer(
        ctx,
        testcontainers.WithImage(""),
        )

    assert.NoError(t, err)

    authServerURL, err := keycloakContainer.GetAuthServerURL(ctx)
    assert.NoError(t, err)

        fmt.Println(authServerURL)

    t.Cleanup(func() {
        assert.NoError(t, keycloakContainer.Terminate(ctx))
    })

results in:
