Ignore utilities.broadband_service from data updates

[steveoh]

This dataset's polygons are "invalid" in postgis because of the differences in sql servers implementation of shape validity. Repairing the invalid geometries (40%) uses all of the time allowed by the serverless function. The shape repair is skipped for this table specifically. But the data import still happens and corrupts the shape.

The import script needs to skip this table entirely to avoid corruption and allow for another method of updating the data.
