IPv6 support

[WietseWind]

Hi!

First of all: thank you for this project & your contributions to open source (!)

Then the reason for this issue:
Currently the hostname unofficial-builds.nodejs.org hostname doens't have IPv6 reachability. This is tricky at IPv6 only networks;

12.65 npm ERR! gyp ERR! configure error 
12.65 npm ERR! gyp ERR! stack FetchError: request to https://unofficial-builds.nodejs.org/download/release/v20.8.0/node-v20.8.0-headers.tar.gz failed, reason: connect ENETUNREACH 45.55.98.129:443

nslookup:

*** Can't find unofficial-builds.nodejs.org: No answer

Adding IPv6 support would be greatly appreciated ;)

Workaround

For now I managed to continue by setting up a reverse proxy, which will be used if you specify the --dist-url when running npm install. Not ideal but it may work for others on IPv6 only networks:

E.g. if you want to install the ed25519 package:

npm --dist-url=https://nodejs-builds.xahau.tech/download/release install ed25519

Why is your gyp trying to install from unofficial builds? The releases here are only for some of the architectures that aren't officially supported, but the headers should be the same as the official release ones.
