Fix dataset tests failing in Airflow 3

[tatiana]

Previously, the following tests were failing:

FAILED tests/operators/test_local.py::test_run_operator_dataset_inlets_and_outlets_airflow_210_onwards - ModuleNotFoundError: No module named 'airflow.models.dataset'

Details:

_______ test_run_operator_dataset_inlets_and_outlets_airflow_210_onwards _______

caplog = <_pytest.logging.LogCaptureFixture object at 0x7f1234faf3a0>

    @pytest.mark.skipif(
        version.parse(airflow_version) < version.parse("2.10"),
        reason="From Airflow 2.10 onwards, we started using DatasetAlias, which changed this behaviour.",
    )
    @pytest.mark.integration
    def test_run_operator_dataset_inlets_and_outlets_airflow_210_onwards(caplog):
>       from airflow.models.dataset import DatasetAliasModel
E       ModuleNotFoundError: No module named 'airflow.models.dataset'

tests/operators/test_local.py:471: ModuleNotFoundError

The test test_run_operator_dataset_url_encoded_names will be handled in the PR #1713

Closes: #1704

Pull Request Overview

This PR fixes failing dataset tests under Airflow 3 by updating import references and assertions to use the Asset alias model instead of the old Dataset alias model, and by removing a skip marker that prevented testing for Airflow 3.

• Updated import logic for AssetAliasModel in test_run_operator_dataset_airflow_210_onwards
• Updated test assertions to use AssetAliasModel instead of DatasetAliasModel
• Removed a skip marker to allow testing dataset emission under Airflow 3

Comments suppressed due to low confidence (1)

tests/operators/test_local.py:576

• The removal of the skip marker for Airflow 3 raises a concern about the test's compatibility; please verify that the updated logic behaves as expected under Airflow 3 conditions.

# TODO: Make test compatible with Airflow 3.0. Issue:https://github.com/astronomer/astronomer-cosmos/issues/1705

The only tests that are failing will work once #1725 is merged and this PR is rebased.
