This is a backport of the PR duckdb#665 to v1.5-variegata stable branch. This PR fixes the output type and value of the `IS_NULLABLE` column of the `DatabaseMetaData#getColumns()` method ([ref](https://docs.oracle.com/javase/8/docs/api/java/sql/DatabaseMetaData.html#getColumns-java.lang.String-java.lang.String-java.lang.String-java.lang.String-)). It was inadvertently broken by duckdb#639 that changed the underlying query to use `duckdb_columns()` instead of `information_schema.columns` view, that returns almost the same columns, but not exactly ([impl](https://github.com/duckdb/duckdb/blob/e64b98f66712b9674897bb27f7f417e5e88fb4be/src/catalog/default/default_views.cpp#L51)). Fixes: duckdb#664
