dashboards-maps [BUG] Country_iso_code SJ has no shape in world map

Describe the bug

The ip2geo plugin/processor correctly assigns the country_iso_code value SJ (Svalbard and Jan Mayen) to IP addresses registered there. However, when using this in a map, the country iso code is not mapped to any geographic area.

To Reproduce Steps to reproduce the behavior:

Create a map visualization, using Bucket type "Shape field".
Use a data source with country ISO codes, where at least one of the values is SJ
Watch the error message pop up in the lower right corner

Expected behavior Svalbard and Jan Mayen (SJ) should be geographically identified on the world map
