fix(cli): use fetch instead of yarn npm info

[jtoar]

Some time ago I think I made the call to use yarn npm info to get information from NPM about a package's version because I didn't want to install yet another dependency. This was the wrong move in hindsight since it meant 1) spawning a child process and 2) while it seemed safe to assume that Redwood projects would have a version of yarn with the npm subcommand, this wasn't true in practice.

Now that fetch is in Node.js, we can just use that like @Josh-Walker-GM has elsewhere:

redwood/packages/cli/src/commands/experimental/setupDockerHandler.js

Lines 330 to 339 in 0193615

	const packumentP = await fetch(`https://registry.npmjs.org/${module}`)
	const packument = await packumentP.json()
	// If the version includes a plus, like '4.0.0-rc.428+dd79f1726'
	// (all @canary, @next, and @rc packages do), get rid of everything after the plus.
	if (version.includes('+')) {
	version = version.split('+')[0]
	}
	const versionIsPublished = Object.keys(packument.versions).includes(version)

I think this might fix the bug you saw when deploying yesterday.

Agreed that doing an API request is likely an improvement over spawning a child process.
