The Compose file './docker-compose.yml' is invalid : enable_ipv6 is not allowed

Hi,

I am on ubuntu 18.04.1, docker 20.10.7 and docker-compose version 1.24.1.

When I try to run SETUP_ONLY=1 ./run-tests.sh, I have the following error messages :

ERROR: The Compose file './docker-compose.yml' is invalid because:
networks.wordpress_bouncer_network_ipv4 value Additional properties are not allowed ('enable_ipv6', 'name' were unexpected)
networks.wordpress_bouncer_network_ipv6 value Additional properties are not allowed ('enable_ipv6', 'name' were unexpected)
networks.wordpress_bouncer_network_ipv6.ipam.config value Additional properties are not allowed ('gateway' was unexpected)

And it seems that enable_ipv6 property is not allowed with version 3 : docker/compose#4958

I changed version "3" by "2.3" and I could run the script, but then (when I tried to test the plugin) I had other errors probably due to this change.

As a workaround, I removed all unallowed additional properties (enable_ipv6, name, gateway) from the docker-compose.yml file: the script ran well, and the plugin seems to work, but I guess I will have issue with IPv6 feature.
