Port forwarding to host

[snaike00]

I encountered a situation where needed to forward ports from Android to Host.
To solve this, you need to enter the container (Linux) and run the following commands:

1. adb forward tcp:3128 tcp:3128
2. socat tcp-listen:3128,bind=YOUR_CONTAINER_LINUX_IP,fork tcp:127.0.0.1:3128

In this example, we successfully forwarded port 3128 (TCP) on dockerify-android:27-08-25

@Shmayro Please add environment variables (-e or --env) for simple port forwarding. This will be much simpler and easier for users.

I've opened PR #45 that adds the environment variable you requested.

Now you can simply use:

PORT_FORWARD=3128:3128 docker compose up

Or for multiple ports:

PORT_FORWARD=3128:3128,8080:8080 docker compose up

No need to manually enter the container anymore!
