az ad app create uses reply url validation on app identity url

**Related command**
`az ad app create`

**Describe the bug**
We have previously been able to create app registration through `az ad app create` with app identity url with a prefixes "app://" and "spn://"

An example of the call:
`az ad app create --display-name "My App Registration" --identifier-uris "app://domain.com/environment/servicename" --enable-access-token-issuance true`

However, the same call now returns the following error: "ERROR: One or more of your reply urls is not valid." Based on some testing, the prefix in the app identity url is now limit to "https://" and "api://". I was last able to create an app registration with app identity url "spn://" on 6/15/2022 in az-cli version 2.37.0.

**To Reproduce**
call "az ad app create" with the parameter `--identifier-uris` provided with a uri that is not prefixed with either "https://" and "api://", such as "app://" or "spn://"

**Expected behavior**
App registration is created.

**Environment summary**
- Install method: MSI
- OS Version: Windows 10.0.19044 Build 19044
- Tested on on azure-cli 2.37.0 and 2.39.0

**Additional context**
The issue was found as we were about to setup our staging environment. We now have to recreate our dev environment app registration to ensure all environments are setup the same way.
I'm not sure if the issue is part of a breaking change in Azure CLI or in Microsoft Graph. However, the breaking change came after the migrate to 2.37.0.
