chore: Add BigQuery Dataframes team to CODEOWNERS with wildcard

Add `@googleapis/bigquery-dataframe-team` as a code owner for BigQuery packages in the repository. Consolidates `google-cloud-bigquery*` packages using a wildcard, and explicitly includes connectors like `pandas-gbq`, `sqlalchemy-bigquery`, and `bigquery-magics`.
