Incoder/coder#13122 a user sees empty values when referencing${data.coder_workspace.me.template_id} in their template. This happens because their coder server version is behind the provider, and this kind of issue will continue to appear as we implement more provider functionality (#220,#219).

There are two things we should do to fix this:

1. In our docs under each attribute and resource, declare the Coder version requirements

2. Replace code like:
   

   terraform-provider-coder/provider/workspace.go

   Lines 83 to 90 in3cc9802

   	templateID:=os.Getenv("CODER_WORKSPACE_TEMPLATE_ID")
   	_=rd.Set("template_id",templateID)
   	templateName:=os.Getenv("CODER_WORKSPACE_TEMPLATE_NAME")
   	_=rd.Set("template_name",templateName)
   	templateVersion:=os.Getenv("CODER_WORKSPACE_TEMPLATE_VERSION")
   	_=rd.Set("template_version",templateVersion)

withLookupEnv andfail the build when a value is missing instead of using blanks.
