az apim api import to existing API clears serviceUrl when the optional --service-url parameter isn't provided

Describe the bug

az apim api import to existing API clears serviceUrl when the optional --service-url parameter isn't provided Clearing/removing/blanking the serviceUrl property of an APIM API is a risk that the runtime breaks down.

Issue script & Debug output

az apim api import 
  --service-name apim-something-weu 
  --resource-group rg-something-weu 
  --path /ecommerce 
  --specification-format OpenApiJson 
  --specification-path C:\something\ecommerce.json 
  --api-id ecommerce-v1 
  --api-version v1 
  --api-version-set-id 'ecommerce' 
  --description "sinterklaas" 
  --display-name eCommerce

Expected behavior

Ensure properties that are not provided, as they are (intentionally) optional, won't be changed via the resulting resource provider deployment.

Additional context

We aim to have this split

APIM configuration via BICEP infra templates
- including API definition (paths, API level policies), (API) Products, subscriptions and such
On the API solution (deploy-time pipeline) we take the OpenAPI spec, and (re)import the operations into the predefined APIM API

The serviceUrl is to be configured and maintained in the former, also to have an environment agnostic OpenAPI specification file. Currently that is impossible as I can't instruct the az apim api import to stay "hands of" the serviceUrl that was configured, and is no cleared as result, breaking the runtime and resulting into unavailability.

Can be reproduced via

Checking the serviceUrl of an API after az apim api list --resource-group rg-something-weu --service-name apim-something-weu
(re)import that API, without specifying a --service-url
Check again the serviceUrl of the same API, which is now converted into a null value.

The error directly after that

GatewayError:
   at forward-request

Backend service URL is not defined.
