Message:

Fix #22179: Add support for GeoPackage in OpenData

This does two things:

1. Add gt-geopkg to the GeoTools plugin and update the GeoTools version to 27.1
2. Adds support int OpenData for GeoPackage. This involved a refactor to make it easier to reuse code between the shapefile support and geopackage. As such, it should be much easier to add additional formats supported by GeoTools in the future, if needed.
