[Bug]: Cannot reuse Selenium BrowserWebDriverContainers under Linux

Beginne in modules/selenium/src/main/java/org/testcontainers/containers/BrowserWebDriverContainer.java etwa bei Zeile 224, wo der /dev/shm-Bind hinzugefügt wird. Reproduziere das Problem mit dem bereitgestellten BuggyTest unter Linux und überprüfe anschließend, dass das Starten desselben BrowserWebDriverContainer nach dem Stoppen nicht mehr mit einem Fehler wegen eines doppelten Mount-Punkts fehlschlägt.

What happened?

When trying to reuse a BrowserWebDriverContainer under Linux, starting the container after stopping it once fails with com.github.dockerjava.api.exception.BadRequestException: Status 400: {"message":"Duplicate mount point: /dev/shm"}. Under Windows the following test succeeds - under Linux it does not.

Reproducer:

import org.junit.jupiter.api.Test;
import org.testcontainers.junit.jupiter.Container;
import org.testcontainers.junit.jupiter.Testcontainers;
import org.testcontainers.selenium.BrowserWebDriverContainer;
import org.testcontainers.utility.DockerImageName;

@Testcontainers
public class BuggyTest {

    @Container
    static final BrowserWebDriverContainer BROWSER_WEB_DRIVER_CONTAINER = new BrowserWebDriverContainer(
           DockerImageName.parse("selenium/standalone-chrome:148.0-20260505")
    );

    @Test
    void testContainer() {
        BROWSER_WEB_DRIVER_CONTAINER.start();
        BROWSER_WEB_DRIVER_CONTAINER.stop();

        BROWSER_WEB_DRIVER_CONTAINER.start(); //this fails
        BROWSER_WEB_DRIVER_CONTAINER.stop();
    }

}

Additional Information

The problem is most likely located in https://github.com/testcontainers/testcontainers-java/blob/main/modules/selenium/src/main/java/org/testcontainers/containers/BrowserWebDriverContainer.java#L224 that adds the /dev/shm bind again, not checking that the bind has been already added previously.
