fix: Remove hardcoded npm registry url

[jasonjiicloud]

Summary:

fixes: #2519
Official npm registry url is hardcoded, the "cli" can't run successfully in a closed environment.

Following error is displayed when running npx @react-native-community/cli@latest init AwesomeProject --verbose.

error fetch failed.

My solution is using getNpmRegistryUrl() to get real npm registry url in user's local environment, then it can avoid using official npm registry directly.

Test Plan:

Build and run node /path/to/react-native-cli/packages/cli/build/bin.js init AwesomeProject

I'd prefer leveraging here new URL() to make sure URL is always in a correct format, e.g. when getNpmRegistryUrl()'d return value without / at the end, previous would've fail.

Suggested change

	const json = await fetch(getNpmRegistryUrl() + '@react-native-community/template').then(
	const json = await fetch(new URL('@react-native-community/template', getNpmRegistryUrl())).then(

Makes a lot of sense, thanks! 👍

This is a really nice change. Couple of small things before you land it:

1. update the URL handling to use URL as @szymonrybczak suggested
2. fix the formatting
