hooks: do not repeat #!/usr/bin/env bash

The comment claims that:
> doesn't matter if `#!/usr/bin/env bash` gets repeated later on in a hooks file

However it is a convetion that there is only one comment like that and
the `setup-hooks.sh` script already takes care of adding it if the file
didn't exist.

Alternatively, we could leave the extra comment and remove the related
code in `setup-hooks.sh`. Currently two comments are added even if the
file didn't exist.
