feat: Replace MyPy with pyrefly type checker (do not merge)
Summary
This PR replaces MyPy with Meta's
pyreflytype checker as a test to evaluate pyrefly as a potential MyPy alternative for the airbyte-python-cdk repository. The integration uses pyrefly's--suppress-errorsauto-noqa feature to automatically add suppression comments for existing type violations, allowing us to focus on evaluating the tool's performance and usability rather than fixing legacy type issues.Key Changes:

--suppress-errorsto focus on tool evaluation rather than fixing existing type issuesThe large number of auto-generated suppressions (530) indicates significant type inconsistencies in the legacy codebase that pyrefly detected. This provides valuable insight into the codebase's type safety status while allowing evaluation of pyrefly's capabilities.
