Pre commit update (#2098)

codespell now sees "falsy" as a mis-spelling of either "false" or "falsely"; adding it since I think this it's occasionally used this way in programming. e.g., https://developer.mozilla.org/en-US/docs/Glossary/Falsy

Adjusts to use the new check-copyright support for lines starting with a dash.
