Filter configuration fails on Drupal 11

The problem is the filter ID. In the existing version, the filter IDs are g2:def and g2:automatic, which does not match the schema names found to be g2_definition and g2_automatic. Aligning on those names removes this issue.

However fixing this shows that validation fails on the stop_list contents, which is expected to be a sequence but is stored as a string.

Merged to current dev HEAD.
