schema:position not used to order chart legends

[FabianCretton]

Describe the bug
An ordinal dimension is used to display a map, the schema:position should be used to order the legend under the chart

To Reproduce

1. Visualize INT or TEST
2. Dataset "waldbrand" which is a draft
3. Choose the map view
4. The labels under the map are ordered alphabetically, and not according to schema:position
5. Seems the same for the table view

Screenshots or video

Environment (please complete the following information):

• Visualize environment and version: INT v3.19.7
• Browser and version: FireFox 110
