Breaks when used in ES Modules context due to requirement for file name extension

[scottdotjs]

Environment: Node 16.13.1 on Windows.

On a project where I have "type": "module" in my package.json, the hooks fail with this error:

scott@Fresh MINGW64 ~/Code/Repos/project (main)$ git checkout hooks-test
Switched to branch 'hooks-test'
M       package.json
M       pnpm-lock.yaml
node:internal/errors:464
    ErrorCaptureStackTrace(err);
    ^

}

When type is "module", the file with the shebang requires a file name extension (according to this answer on StackOverflow). That's obviously incompatible with Git's requirement for hooks not to have a file name extension. I'm not sure if there's a solution to that.
