removed exclude module and added \n to cli command

Motivation

In the process of running test for the release, we discovered 2 issues that this pr aims to address.

• An error raised by pyinstaller Target module "importlib_resources" already imported as "ExcludedModule('importlib_resources',)".
• An error raised in the Pro Non-Docker Smoke Test

❌ Error: EOF when reading a line
LocalStack extension.):   [3/9] project_slug (my-localstack-extension):   [4/9] module_name (my_localstack_extension):   [5/9] class_name (MyLocalstackExtension):   [6/9] full_name (Jane Doe):   [7/9] email ([email protected]):   [8/9] github_username (janedoe):   [9/9] version (0.1.0): 

Changes

• Removed --exclude-module importlib_resources \ to prevent import conflict issue as importlib_resources is vendored with setuptools
• Added an extra line to the create script as a new option now exists when creating an extension with the localstack extensions dev new command

Thanks for jumping on this!
The changes are looking good, but the changes to the extensions tests mean that a breaking change slipped in there. We should double-check if that is on purpose...

nothing intentional going on here, but this is a developer command, so no need to worry too much about a breaking change
