Prevent naming the plugin 'lean'

[zzuga]

Steps to reproduce and a minimal demo of the problem

Run the new-wp-plugin generator as described here and name the plugin 'lean'

Current behavior

You will notice the the Acf helper functions stop working.

Expected/desired behavior

Acf helper functions should keep on working.

Other information

The namespace for the generated wp-plugin/src/Acf.php is conflicting with the one for wp-acf package, so none of the Acf helper functions work. Running composer install says:

Warning: Ambiguous class resolution, "Lean\Acf" was found in both "$baseDir . '/src/Acf.php" and "/var/www/api.lean.dev/htdocs/wp-content/plugins/lean/vendor/moxie-lean/wp-acf/src/Acf.php", the first will be used.
