feat: ZEP-0032 support 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).

Hey @touchardv, thanks for putting together this PR! Our CI linters are currently failing on the changed CLI flags. We have some automation to fix this -- running make docs-and-schema locally will update the markdown files for you. Pushing up the resulting diffs ought to resolve the failed check.
