Remove deprecated punycode throwing deprecation warning to stderr

[alfonsrv]

I am using mjml which depends on juice, which in turn depends on web-resource-inliner, throwing the following warning to stderr: (node:60710) [DEP0040] DeprecationWarning: The "punycode" module is deprecated. Please use a userland alternative instead.

punycode → node-fetch → web-resource-inliner → juice

Any alternative to work around this or way to fix this?
