added RemoteTFENumericVersion() for TFE numeric version

[skj-skj]

Description

from TFE 1.1.0 & 1.0.3, we have added X-TFE-Current-Version header which returns TFE numeric version value. this pr adds new function/method RemoteTFENumericVersion to client interface which returns TFE numeric version string, and for earlier TFE versions the function will return empty string

Testing plan

1. spin up TFE 1.1.0 or 1.0.3
2. create token to create admin docker exec -t terraform-enterprise-tfe-1 tfectl admin token
3. create admin user and grab the user tfe token

   curl -X POST 'https://tfe.example.com/admin/initial-admin-user?token=your-token' -H 'Content-Type: application/json' -d '{"username":"admin","email":"admin@example.com","password":"somePASS123!@#"} | jq -r '.token''

4. create new directory, run:

     go mod init main
     go get github.com/hashicorp/go-tfe@b682c9a94293397c76d083ce9e93f968ef967964

5. run go mod tidy
6. create main.go file with below content:

   // Example code to print the remote TFE numeric version.
   package main
   
   import (
       "fmt"
    	"log"
   
   	tfe "github.com/hashicorp/go-tfe"
   )
   
   func main() {
   
   	config := &tfe.Config{
   		Address: "https://tfe.example.com",
    		Token:   "your-tfe-token",
   	}
   
   	client, err := tfe.NewClient(config)
   	if err != nil {
   		log.Fatal(err)
   	}
   
   	fmt.Printf("Remote TFE Numeric Version: %s\n", client.RemoteTFENumericVersion())
   }

7. run go run main.go
