Subject: [PATCH] punycode: limit deprecation warning

DEP0040 is an extremely annoying warning. Most of the people
seeing it cannot do anything about it. This commit updates the
warning logic to only emit outside of node_modules. This is
similar to other warnings such as the Buffer() constructor
warning.

Ideally, this should be backported to Node 22.
