## Summary

<!-- What's the purpose of the change? What does it do, and why? -->

As discussed in
https://github.com/astral-sh/ruff/issues/14626#issuecomment-2766146129,
we're to separate suggested changes from required changes.

The following symbols have been moved to AIR311 from AIR301. They still
work in Airflow 3.0, but they're suggested to be changed as they're
expected to be removed in a future version.

* arguments
    * `airflow..DAG | dag`
        * `sla_miss_callback`
    * operators
        * `sla`
* name
* `airflow.Dataset] | [airflow.datasets.Dataset` → `airflow.sdk.Asset`
    * `airflow.datasets, rest @ ..`
        * `DatasetAlias` → `airflow.sdk.AssetAlias`
        * `DatasetAll` → `airflow.sdk.AssetAll`
        * `DatasetAny` → `airflow.sdk.AssetAny`
* `expand_alias_to_datasets` → `airflow.sdk.expand_alias_to_assets`
        * `metadata.Metadata` → `airflow.sdk.Metadata`
    <!--airflow.models.baseoperator-->
    * `airflow.models.baseoperator.chain` → `airflow.sdk.chain`
* `airflow.models.baseoperator.chain_linear` →
`airflow.sdk.chain_linear`
* `airflow.models.baseoperator.cross_downstream` →
`airflow.sdk.cross_downstream`
* `airflow.models.baseoperatorlink.BaseOperatorLink` →
`airflow.sdk.definitions.baseoperatorlink.BaseOperatorLink`
    * `airflow.timetables, rest @ ..`
* `datasets.DatasetOrTimeSchedule` → *
`airflow.timetables.assets.AssetOrTimeSchedule`
    * `airflow.utils, rest @ ..`
        <!--airflow.utils.dag_parsing_context-->
