git hooks are always #!/usr/bin/env bash even when bash is not available on the system

Summary

title pretty much says it all.
Reproduce by using a container image like something alpine based (and that specifically doesn't have bash installed).

1. install prek
2. install hooks via prek install
3. Open .git/hooks and check any of the relevant (real) hook files
4. you'll see the first line is #!/usr/bin/env bash

Platform

docker image python:3.14.2-alpine3.23

Version

Log file

This won't happen when running prek directly; it's an issue with the hooks files that prek generates when running prek install. Run prek install and then examine the created hooks files
