precommit hook broken

Moving the entry point broke the pre-commit hook in the repo

I am not sure what the best way is to handle it.
As args in the hook are overriden by user supplied ones, using the betterbib entry point seems to be a bad idea.
What do you think about adding dedicated scripts for the hooks (probably in their own directory) just importing the methods from the cli folder for now @nschloe ?
