Proposed Commit Message

ci: ignore import errors from crypt as stop-gap for check_format

python-3.13+ no longer ships crypt which breaks tox -e mypy and
check_format operations with typing import error.

Upstream cloud-init already handles ImportError fallback to use
passlib in environments when crypt is unavaiable.

Provide a stop-gap for check_format passes in CI while upstream
confirms with distribution and platform vendors that there are
no environments which still provide crypt instead of passlib.

Additional Context

upstream PR to drop crypt import will follow to replace this stop-gap
