Ability to specify the image pull policy in the DockerComposeContainer

Hi!
I suggest adding the ability to specify the image pull policy to DockerComposeContainer. There is currently no way to tell DockerComposeContainer to pull the latest version of images from the remote repository when the image is already present in the local repository.

I believe that we can follow the analogy with the one implemented in org.testcontainers.containers.GenericContainer and add the method withImagePullPolicy to the DockerComposeContainer. In this case, the pull policy will be applied to all images that are found in docker-compose config files.
An alternative option would be, for example, specifying the image pull policy for individual services.

I am ready to implement this feature and await feedback.

Inizia con DockerComposeContainer e confronta l’implementazione e l’API di GenericContainer per image-pull-policy. Traccia il modo in cui vengono gestite le immagini provenienti dalla configurazione di Docker Compose, quindi definisci e testa il comportamento della policy richiesto per tali immagini, incluso se si applica globalmente o per servizio.
