Presence of .terraform-version makes terragrunt fail

[arengifo-lbx]

Describe the bug
When running the terragrunt action in a folder that contains a .terraform-version file, the action install the terraform version specified in the tf_version input rather than use the version specified in .terraform-version. Then, when terragrunt runs the action (i.e. "plan"), it fails because cannot find the terrafom binary version specified in .terraform-version

To Reproduce
Create a .terraform-version that specifies a version different than the defined in tf_version input

Expected behavior
Terragrunt action should first look for the presence of .terraform-version to decide which version to install. This code could make a difference:

  if [ -f .terraform-version ]; then
    tfversion=$(cat .terraform-version)
    log "Installing Terraform version ${tfversion}"
    mise install terraform
  fi
  log "Installing Terraform version ${version}"
  mise install terraform@"${version}"

Nice to have
