fix: Trino union selects - #465
Merged

Conversation
Since Trino 482, the `lower_bounds` and `upper_bounds` columns of the `$files` metadata table changed from `map(integer, varchar)` to typed `row` values. This broke the union which requires the fields from the first select to match names and types for any union selects. Co-authored-by: Techassi <git@techassi.dev>
