Fix: Handle Slack rate limits and add GitHub org repo support

This commit includes two main improvements:

1. Slack Connector (`slack_history.py`):
   - Addresses API rate limiting for `conversations.list` by introducing a 3-second delay between paginated calls.
   - Implements handling for the `Retry-After` header when HTTP 429 errors occur.
   - Fixes a `SyntaxError` caused by a non-printable character accidentally introduced in a previous modification.
   - Adds comprehensive unit tests for the rate limiting and retry logic in `test_slack_history.py`.

2. GitHub Connector (`github_connector.py`):
   - Modifies `get_user_repositories` to fetch all repositories accessible by you (including organization repositories) by changing the API call parameter from `type='owner'` to `type='all'`.
   - Adds unit tests in `test_github_connector.py` to verify this change and other connector functionalities.
