Move to listr2 when v6 is out of beta

[tommy-mitchell]

Per #683 (comment), this is a reminder issue: https://github.com/listr2/listr2

[sindresorhus]

It's out of beta now.

Tasks could also be consolidated / moved into their own subdirectory for better organization as part of this.

np/source/index.js

Lines 90 to 103 in ad7b09e

	const tasks = new Listr([
	{
	title: 'Prerequisite check',
	enabled: () => options.runPublish,
	task: () => prerequisiteTasks(input, pkg, options),
	},
	{
	title: 'Git',
	task: () => gitTasks(options),
	},
	], {
	showSubtasks: false,
	renderer: options.renderer ?? 'default',
	});

Potential blocker: listr2/listr2#676

np's pretask UI uses inquirer, whereas listr2 only supports enquirer for now. np currently only prompts during the task list when getting an OTP.

Until listr2 also supports inquirer, we'd either need to change over to enquirer (which involves changing the test mocking), or use inquirer for the pretask UI and enquirer to prompt for an OTP.

---

I have a local branch where I've moved everything over to listr2 except the OTP prompting. I think we can remove rxjs as well once that's updated, as it seems like the other uses were to work around some old execa shortcomings.

Ideally, we would switch to Ink, but that's a much bigger task.

It looks like listr2 v7 supports Inquirer.

Ideally, we would switch to Ink

Why isn't listr2 just based on Ink? It feels like using Ink directly would be too big of a task and an unnecessary one at that. Maybe vadimdemedes could make such a package, if it doesn't already exist.
