Support OpenTF :-)

When it's available, we should try and support both opentf and terraform.

It seems to go quite fast, as @mvantellingen showed: https://www.linkedin.com/feed/update/urn:li:activity:7102220552966131713/

probably tenv will help you to easily switch from terraform to opentofu: https://github.com/tofuutils/tenv
