feat: initial support for IPv6 only

[touchardv]

Description

Initial support for IPv6 only mode with zarf.
Use of HTTP and localhost is kept in IPv6 mode (to avoid the need for dealing with registry configuration in the k8s container runtime) by using a socket proxy (currently a basic socat Alpine container image).

It is a work-in-progress and some further changes are required to:

• Package the proxy container image with the injector registry (already supported by zarf)
• Update the Rust injector to support serving the proxy image.
• Fix the broken tests.
• Add additional tests to cover the changes.
• Find an alternative solution for running the proxy (???)
