Add @task.analytics Decorator

[gopidesupavan]

Follow-up to #62232 which introduced the AnalyticsOperator.

This PR adds TaskFlow API support for the AnalyticsOperator via the @task.analytics decorator.

Usage Example

from airflow.providers.common.sql.config import DataSourceConfig
from airflow.sdk import DAG, task

datasource_config = DataSourceConfig(
    conn_id="aws_default", table_name="users_data", uri="s3://bucket/path/", format="parquet"
)

with DAG(dag_id="example_analytics_decorator") as dag:

    @task.analytics(datasource_configs=[datasource_config])
    def get_user_summary_queries():
        return ["SELECT * FROM users_data LIMIT 10", "SELECT count(*) FROM users_data"]

    @task.analytics(datasource_configs=[datasource_config], result_output_format="json")
    def get_filtered_user_queries(limit: int = 50):
        return [f"SELECT * FROM users_data LIMIT {limit}", "SELECT count(*) FROM users_data"]

    get_user_summary_queries() >> get_filtered_user_queries(limit=25)
