Update tfenv tool

[kvendingoldo]

Hi. Great repo! I see that you use tfenv here:

dotfile/zshrc

Line 155 in 7d7f3f8

zsh-tfenv

I suggest you to switch to tenv: https://github.com/tofuutils/tenv:

• it is a successor of tofuenv and tfenv
• can manage versions of OpenTofu / Terraform / Terragrunt and Atmos
• does not require any dependencies like jq / bash / etc
