Feature Request: add support for OpenTofu

I am proposing adding an [OpenTofu](https://github.com/opentofu/opentofu) feature to support the open-source community's adoption of OpenTofu as the future of Terraform. OpenTofu emerged as a compelling alternative in light of Terraform's recent licensing changes. [See manifesto](https://opentofu.org/manifesto)

**Why?**
- It operates under open-source governance, making it a reliable choice.
- It has strong backing from various industry leaders.
- It's designed to be backward-compatible with existing Terraform projects.
- It has been officially accepted into the [Linux Foundation](https://www.linuxfoundation.org/press/announcing-opentofu).
