Node22 DeprecationWarning due node-fetch 2.x

[Kurre]

It seems that node-fetch v2.x is causing DeprecationWarning on Node22 (maybe in Node21 too?) due usage of deprecated punycode module. node-fetch 2.x is only receiving security fixes so this issue won't most likely be resolved without upgrading the node-fetch dependency to 3.x.

references from other repos:

• Upgrade node-fetch dependency to v3.2 googleapis/gaxios#508 & feat!: Upgrade to node-fetch v3 googleapis/gaxios#617

edit: simplified example

Expected Behaviour
No warnings

Actual Behaviour

(node:16845) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.

I was tinkering a bit with this one, and if the supported Node.js versions are 18, 20 (and 22), then it should be possible to just replace the node-fetch with Node's own fetch implementation.

I made a quick'n'dirty PoC of this variation, and it seems to be a possible way to proceed. Some tests for modules are failing, but probably nothing too serious 🤔
