`/sites/{site_id}/deploys/{deploy_id}/restore` returns 200 instead of 201

[jedevc]

restoreSiteDeploy is documented as returning 201 on creation.

open-api/swagger.yml

Lines 1164 to 1183 in 166c074

	/sites/{site_id}/deploys/{deploy_id}/restore:
	post:
	operationId: restoreSiteDeploy
	tags: [deploy]
	parameters:
	- name: site_id
	type: string
	in: path
	required: true
	- name: deploy_id
	type: string
	in: path
	required: true
	responses:
	'201':
	description: Created
	schema:
	$ref: '#/definitions/deploy'
	default:
	$ref: '#/responses/error'

However, in practice, it appears that this API instead returns 200 on success. When using the go API, this gives the following error:

unexpected success response: content available as default response in error (status 200): {"Payload":{"message":""}}

open-api/go/plumbing/operations/operations_client.go

Lines 3905 to 3907 in 166c074

	// unexpected success response
	unexpectedSuccess := result.(*RestoreSiteDeployDefault)
	return nil, runtime.NewAPIError("unexpected success response: content available as default response in error", unexpectedSuccess, unexpectedSuccess.Code())

(even though the operation has succeeded, and the deployment has been correctly restored).

It should be pretty easy to update the spec - but also not sure whether maybe the API is instead returning the incorrect status?
