When running fern init, I see the following warning:

[DEP0040] DeprecationWarning: The punycode module is deprecated. Please use a userland alternative instead.

To reproduce

Steps to reproduce the behavior:

Reproducible with Node 21

Node LTS (20.11.0) will not show deprecation warning

@atupem if you downgrade your Node version to v20, does this get rid of the warning?

[HLFH]

I currently have Node v22.6.0 and I still have this warning.

And I still have it with a downgrade to node@20 with Homebrew.

fern --version
(node:15952) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
(Use `node --trace-deprecation ...` to show where the warning was created)
0.39.10
➜  ~ node --version
v20.16.0

I am also seeing this

Node version: v22.6.0
Fern version: 0.39.16

Confirming this is still an (annoying) deprecation notice.

Node version: v23.4.0
Fern version: 0.46.2

Looks like there was an attempted fix by @dsinghvi #5142 that did not remove the warning
