docksal: host.docker.internal not working

When using docksal with Docker for Mac, it seems that host.docker.internal (documented here: https://docs.docker.com/docker-for-mac/networking/) doesn’t work.

Steps to reproduce the issue:

Install docksal and init new project using the default stack as per the official docksal documentation.
docker exec -it [WEB_CONTAINER] sh
then inside the container run: ping host.docker.internal

Results: ping: bad address 'host.docker.internal'

Expected results:

PING host.docker.internal (192.168.65.2): 56 data bytes
64 bytes from 192.168.65.2: seq=0 ttl=37 time=1.007 ms
64 bytes from 192.168.65.2: seq=1 ttl=37 time=0.357 ms
...

I have tested the same ping in another container that is not created by docksal just to check if there is a problem with my local docker instance, and it’s working there as expected.
