bug: Unable to install erlang without IPv4

[PrestonL]

Describe the Bug

asdf is unable to install erlang or search packages without an IPv4 gateway

Steps to Reproduce

Install asdf-vm onto a machine with IPv6-only network access. Even with NAT64, asdf-vm will hang and fail as it requires IPv4

Expected Behaviour

asdf-vm should work with IPv6-only environments

Actual Behaviour

asdf-vm hangs when operating in an IPv6-only environment

Environment

Any linux machine with IPv6-only networking

asdf plugins affected (if relevant)

No response

I believe git and curl are the only tools we use that hit the network, so I assume this would be a flag we would need to enable for these to work as described. Help welcome 👍
