Add Spector mock API test for azure response-as-bool

[Copilot]

Adds Python SDK mock API test coverage for the azure/client-generator-core/response-as-bool Spector case (Azure/typespec-azure#4328), which adds a Python client namespace to the spec exercising the @responseAsBool decorator.

Changes

• eng/scripts/ci/regenerate-common.ts: Removed azure/client-generator-core/response-as-bool from SKIP_SPECS so the spec is now regenerated for Python (the Python client namespace added in http-client-java, remove unused namer module #4328 unblocks generation).
• tests/mock_api/azure/test_azure_client_generator_core_response_as_bool.py (+ async counterpart under asynctests/): New tests asserting the @responseAsBool HEAD operations map status to bool — 204 → True, 404 → False.
• .chronus/changes: Internal changelog entry.

def test_exists(client: ResponseAsBoolClient):
    assert client.head_as_boolean.exists() is True      # HEAD /exists -> 204

def test_not_exists(client: ResponseAsBoolClient):
    assert client.head_as_boolean.not_exists() is False  # HEAD /exists/not-exists -> 404

The pinned @azure-tools/azure-http-specs@0.1.0-alpha.42-dev.0 already contains the Python namespace, so no dependency bump was required.
