Add support for OpenTofu instead of Terraform

[ptpu]

📝 Brief description

Hey, since Terragrunt version 0.52.0 makes it possible to use OpenTofu instead of Terraform, it would be important to include OpenTofu as an alternative in this Docker container.

Hey! Thank you for letting me know it's needed. I'll work on it in some spare time.

Hello, I've added it to the newest release https://github.com/devops-infra/docker-terragrunt/releases/tag/tf-1.7.5-tg-0.55.20

At this moment if you need to have a support of Terraform as well as OpenTofu (and Terragrunt :) ) in one tool you can use https://github.com/tofuutils/tenv which my team wrote some months ago. A lot of users switched to that tool to unify version management in the world of Terraform.

You're welcome to open any issues or contribute to tenv.

@kvendingoldo I had a look at tenv but it works in a completely different way than expected here. It's more for local environments, not remote ones.
