Describe the bug

The pre-commit hook fails with an issue with black that seems unrelated to the commit itself.

See https://github.com/MDAnalysis/UserGuide/actions/runs/33778483285/job/100726038569?pr=443

Expected behavior
pre-commit runs all tools

Actual behavior

pre-commit run --show-diff-on-failure --color=always --all-files

                  Describe the bug

                  The pre-commit hook fails with an issue with black that seems unrelated to the commit itself.

                  See https://github.com/MDAnalysis/UserGuide/actions/runs/33778483285/job/100726038569?pr=443

                  Expected behavior
                  pre-commit runs all tools

                  Actual behavior

                  pre-commit run --show-diff-on-failure --color=always --all-files
