[CHORE] Edit 'make-hooks' command to install pre-commit script

[colin-ho]

I noticed after following the contributing guide and running 'make hooks', the pre-commit hooks did not run when I commit changes.

Not sure if this was intended, but looking at https://pre-commit.com/#pre-commit-install-hooks:

pre-commit install-hooks does not install the pre-commit script. 
To install the script along with the hook environments in one command, use pre-commit install --install-hooks.
