Convert init.sh into a Composer PHP script for create-project

[kasparsd]

Convert the logic in init.sh into a Composer PHP script that would allow us to simplify the setup down to a single command of composer create-project xwp/block-scaffolding-wp.

[derekherman]

The Bash script accepts input from the command line, how would this work with composer create-project?

This requires converting the Bash script into a PHP script that is cross-platform. Here is the initial prototype for it that can be updated to have the feature parity with what is currently in the init.sh. Notice how it prompts for things:

block-scaffolding-wp/scripts/composer/PluginScaffolder.php

	$io = $event->getIO();
	$default_package_name = sprintf(
	'%s/%s',
	self::TEMPLATE_VENDOR,
	self::TEMPLATE_SLUG
	);
	$desired_package_name = $io->ask(
	'Enter the desired package name (vendor/plugin-name): ',
	$default_package_name

	self::slug_to_string_map( $package->vendor(), $package->slug() )
