Description

Add Azure CLI support for the Isolated v4 App Service Environment SKUs documented at https://learn.microsoft.com/azure/app-service/environment/app-service-configure-isolated-v4-tier:

• Accept I1V4-I6V4 and I1MV4-I5MV4 for az appservice plan create/update
• Map these SKUs to the IsolatedV4 ARM tier
• Require an App Service Environment and allow zone-redundant plans
• Update command help and release history
• Add regression coverage for all supported Isolated v4 SKUs

Testing

• python3 -m pytest src/azure-cli/azure/cli/command_modules/appservice/tests/latest/test_appservice_validators_thru_mock.py -q
• python3 -m pytest src/azure-cli/azure/cli/command_modules/appservice/tests/latest/test_webapp_commands_thru_mock.py::TestCreateAppServicePlanDefaults -q
• python3 -m flake8 on all changed Python files
• Verified a local az appservice plan create ... --sku I1V4 invocation proceeds past argument and SKU validation to ASE lookup

Pull request overview

Adds Azure CLI support for App Service Environment (ASE) Isolated v4 plan SKUs by recognizing the new SKU names and mapping them to the appropriate tier used in plan creation/update flows.

Changes:

• Introduces ISOLATED_V4_SKUS and uses it to map I*V4/I*MV4 SKUs to the IsolatedV4 tier.
• Extends App Service plan SKU validation and parameter enums to accept Isolated v4 SKUs and treat them as ASE-only.
• Adds unit tests covering Isolated v4 tier mapping and ASE requirement, and updates release history.
