refactor(community-cli-plugin): use node builtin fetch (#47397)

Summary:
Removed `node-fetch` in favour of node builtin fetch to get rid of the deprecated `punycode` warning when using Node 22.

`react-native/community-cli-plugin` already requires Node >= 18 where it was made available by default (without `--experimental-fetch` flag).

This change is similar to the one made in https://github.com/facebook/react-native/pull/45227

## Changelog:

[GENERAL] [CHANGED] - Drop node-fetch in favor of Node's built-in fetch from undici in `react-native/community-cli-plugin`

Pull Request resolved: https://github.com/facebook/react-native/pull/47397
