tenv tf use uninformative error if no terraform version installed

[Nmishin]

Describe the bug
If I run tenv tf use 1.2.0 I expect that terraform version will be switched to the needed version, or i will have an error like "version should be installed"

To Reproduce
For now I have no error, or additional log message

$ tenv tf use 1.2.0
Written 1.2.0 in /Users/nmishin/.tenv/Terraform/version
$ terraform version
Failure during terraform call : fork/exec /Users/nmishin/.tenv/Terraform/1.2.0/terraform: no such file or directory

Expected behavior
I want to have some error log

Environment (please complete the following information):
$ tenv --version
tenv version 2.0.7

Will be fixed by #165

Seem to work as expected

$ tenv tf use latest works good if no versions present locally.
$ tenv tf use latest will use the last one version presented locally, I'm not sure that this is expected behaviour, but this is different question.

Could you please try to reproduce the issue like this:

$ tenv tf list
* 1.2.0 (set by /Users/nmishin/.tenv/Terraform/version)
  1.3.0
  1.5.7
  1.6.0
  1.6.1
  1.8.0
$ tenv tf use 1.3.7
Written 1.3.7 in /Users/nmishin/.tenv/Terraform/version
$ terraform version
Failure during terraform call : fork/exec /Users/nmishin/.tenv/Terraform/1.3.7/terraform: no such file or directory
$ tenv --version
tenv version 2.1.6

Got it, you use a specific version, so tenv did not search what it mean in either case, and the message did not help, we should improve that...

$ tenv tf use latest will use the last one version presented locally, I'm not sure that this is expected behaviour, but this is different question.

In my opinion, we don't need to manage that, because Terraform and OpenTofu already warn there user when a new version is available
