chore: deprecate node-fetch in favor of fetch

[XavierGeerinck]

node.js will switch to a built-in fetch from 18.X (FINALLY) which will allow us to deprecate node-fetch (which is outdated as it requires module support from 3.X

Current LTS is 16 but 18 becomes LTS at 25/OCT (https://github.com/nodejs/release#release-schedule)

So target : v3.0.0 of the Dapr JS SDK
