Fixes acrcssc compatibility with recent Azure CLI versions and the split Azure Container Registry Tasks SDK.

The extension could fail when managing supply-chain workflows because it accessed task operations through the general Container Registry client and used legacy SDK method and model names. This resulted in errors such as missing attributes and unsupported arguments when creating a task run request.

Changes

• Use the dedicated ACR Tasks client and models when available, with fallback support for older Azure CLI versions.
• Support both current synchronous task operations and legacy operations.
• Use the correct task-run values field for each SDK generation.
• Wait for legacy long-running update, delete, scheduling, and cancellation operations to complete.
• Add compatibility tests covering current and legacy ACR Tasks SDK behavior.
• Update the extension version and release history to 1.0.0b8.

Hi Cesar Gray (@cegraybl),
Please write the description of changes which can be perceived by customers into HISTORY.rst.
If you want to release a new extension version, please update the version in pyproject.toml (or setup.py, if the extension has not migrated yet) as well.

• This adds the current synchronous schedule_run path, but the compatibility tests only exercise scheduling through begin_schedule_run; the current dry-run/trigger path is not invoked with a synchronous client. Add a focused test for _trigger_task_run or acr_cssc_dry_run that asserts the direct result's run_id is consumed and no LongRunningOperation is used.

    schedule_run, is_long_running = _get_task_operation(
        acr_task_registries_client,
        "schedule_run")
    queued_run = schedule_run(
        resource_group,
        registry.name,
        request)
    if is_long_running:
        queued_run = LongRunningOperation(cmd.cli_ctx)(queued_run)
