Don't scaffold pycache or pyc

[cidrblock]

Related #164

When ansible-creator is installed by pip, some pycache and pyc files are created in the collection unit test directory:

(venv) m910x ➜  test tree venv/lib/python3.12/site-packages/ansible_creator/resources/new_collection/tests/unit/                                   
venv/lib/python3.12/site-packages/ansible_creator/resources/new_collection/tests/unit/
├── __pycache__
│   └── test_basic.cpython-312.pyc
└── test_basic.py

These cause a traceback when scaffolding:

test ansible-creator init --project collection collection=a.b --init-path /tmp/foo --force      
 Warning: re-initializing existing directory /tmp/foo

Not caught in our tests because it's not run from an installed package.

Found during adt tests for server b/c the server was throwing a 500
