MINOR: Add edgeDeployment confirmation request.

[jeremy-cxf]

Adds confirmation endpoint response from:
https://docs.fastly.com/en/ngwaf/edge-deployment

Would be useful for any CLI utility or internal lib to have the ability to query this using the package (e.g "do I already have a service mapped")

Implementation:

	edgeDeployment, err := sc.GetEdgeDeployment("jeremy", "mysite")
	if err != nil {
		return err
	}
	fmt.Printf("%+v\n\n\n\n", edgeDeployment)

	for _, edgeWAF := range edgeDeployment.ServicesAttached {
		fmt.Println(edgeWAF.ID)
		fmt.Println(edgeWAF.CreatedBy)
		fmt.Println(edgeWAF.Created)
		fmt.Println(edgeWAF.AccountID)
	}

Output:

{AgentHostName:moop.edgecompute.app ServicesAttached:[{ID:1KpBNBo1SqpppqIIZ1GRR3 AccountID:6u7fz9eLFkR1kMF2ediYJz Created:2024-04-24 16:05:21 +0000 UTC CreatedBy:[email protected]}]}

Did not add a test because I did not see tests for related endpoints, however can add those if time allows.
