net/http: disable fetch on NodeJS

Browse Source 
NodeJS 18 introduced support for the fetch API for
making HTTP requests. This broke all wasm tests
that were relying on NodeJS falling back to the fake
network implementation in net_fake.go. Disable
the fetch API on NodeJS to get tests passing.

Fixes #57613
