📄 Description

Currently terravision hardodes the TF version in its Dockerfile. This makes it difficult to use terravision with TF setups that differ from the upstream image versions.

This PR adds tfenv to the Dockerfile and invokes tfenv only when TFENV_TERRAFORM_VERSION has been specified, which then downloads and installs the specified TF version before invoking terravision:

Example: specifying no custom Terraform version:

> docker run -e TFENV_TERRAFORM_VERSION=1.13.0 test draw --source .
