tests: add pytest.ini to set asyncio_default_fixture_loop_scope

Recent versions of pytest-asyncio and pytest introduced
stricter handling of asynchronous fixtures. If the
'asyncio_default_fixture_loop_scope' option is unset, async fixtures may
emit DeprecationWarnings during pytest configuration. This can break tests
using pytester by preventing pytest from generating a terminal summary.

This prevents the warning and ensures consistent and stable test execution
for async tests.
