[Docs] Limitations of top metrics agg are not fully documented #72889
Description
We have tested the top_metrics agg as a replacement for top_hits in Lens, and found that the docs are not as accurate as we hoped. Here are the differences from the docs:
- Top_metrics does not work with multi-value arrays, might be related to Use ValuesSourceRegistry for MultiValuesSourceAggregations #53194
- Top_metrics does work with booleans
- Top_metrics does not support scripting
