Update flake8-tabs (PR #10391)
Use continuation-style=hanging option to reduce confusion around alignment styles.
Flake 8 will now issue an error (ET113) for code that would be interpreted as intending vertical alignment style.
Comments no longer trigger the vertical alignment interpretation.
Extends #10050 now that https://gitlab.com/ntninja/flake8-tabs/issues/1 is closed.
Closes: #10021
