Review Comment:
According to the issue https://github.com/apache/airflow/issues/42713, the
response schema should match the format defined here:
https://github.com/apache/airflow/blob/main/airflow/www/views.py#L1035. The
`selected` field indicates whether the tag is selected based on the query
parameters in all `dag_tags`.
