fix black linter failures with action update

[JessicaS11]

Checks that passed yesterday are failing today even without changes to the files causing the failures. Specifically, running black locally results in no reformatting, but then the linting action fails. Likely related to psf/black#4173 and the update of the action to v24.1.0. This PR manually fixes the newline issues causing the linting check failures.
