When using `pre-commit run --all-files`, files explicitly passed to
black are processed even if they don't match the `include` configuration
option. For some reason, (only) one of the `*.py-tpl` files is picked up
by pre-commit. We can avoid this by explicitly excluding certain
patterns of files for the black hook in the pre-commit configuration.
