terraform-docs issue in v1.93.0: invalid command code R

[BeneHa]

Describe the bug

When I run pre-commit run -a terraform_docs with version 1.93.0 I always get the error:

❯ pre-commit run -a terraform_docs --verbose
Terraform docs...........................................................Failed
- hook id: terraform_docs
- duration: 1.1s
- exit code: 1

sed: 1: "README.md": invalid command code R

How can we reproduce it?

It happens no matter if a README.md already exists or not.
