Question: exposing shfmt

[dycw]

Hi, I don't have any experience with go, but would like to expose shfmt as a hook. If I define in .pre-commit-hooks.yaml:

 - id: shfmt
   name: shfmt
   entry: shfmt
   language: golang
   types: [shell]
   additional_dependencies: [github.com/mvdan/sh/cmd/shfmt]

which is my attempt at mimicking #1785, I get:

 ❯ pre-commit try-repo . shfmt --verbose --all-files
[WARNING] Creating temporary repo with uncommitted changes...

        go mod init

No idea what that means. Any help please?

dupe #1815 -- it'll get released soon, I want to get the R branch in before the next release
