Lorenze/better env vars setup enterprise tools (#343)

* refactor: remove token validation from EnterpriseActionKitToolAdapter and CrewaiEnterpriseTools

This commit simplifies the initialization of the EnterpriseActionKitToolAdapter and CrewaiEnterpriseTools by removing the explicit validation for the enterprise action token. The token can now be set to None without raising an error, allowing for more flexible usage.

* added loggers for monitoring

* fixed typo

* fix: enhance token handling in EnterpriseActionKitToolAdapter and CrewaiEnterpriseTools

This commit improves the handling of the enterprise action token by allowing it to be fetched from environment variables if not provided. It adds checks to ensure the token is set before making API requests, enhancing robustness and flexibility.

* removed redundancy

* test: add new test for environment token fallback in CrewaiEnterpriseTools

This update introduces a new test case to verify that the environment token is used when no token is provided during the initialization of CrewaiEnterpriseTools. Additionally, minor formatting adjustments were made to existing assertions for consistency.

* test: update environment token test to clear environment variables

This change modifies the test for CrewaiEnterpriseTools to ensure that the environment variables are cleared before setting the test token. This ensures a clean test environment and prevents potential interference from other tests.

* drop redundancy
