fix: 'AlexaLogin' object has no attribute 'delete_cookiefile' (#2471)

* Update __init__.py

Added `if callable(getattr(os,'delete_cookiefile', None)):`
for compatibility with alexapy<=1.28.2

* Update __init__.py

Class was wrong
Needs to be `AlexaLogin,'delete_cookiefile'`

* style: auto fixes from pre-commit.com hooks
