[Docs] Try to make it clear drilldows only available in dashboard (#1…

…61469)

## Summary

Issue [raised on
Slack](https://elastic.slack.com/archives/C0D8P2XK5/p1688661541837369)
that it was a bit unclear on our [docs
page](https://www.elastic.co/guide/en/kibana/8.8/maps-create-filter-from-map.html#maps-spatial-filters)
that to use drilldowns you had to embed your map in Dashboard, and can't
be used from the Maps application.

 A spatial filter narrows search results to documents that either intersect with, are within, or do not intersect with the specified geometry.
 
-You can create spatial filters in two ways:
-
-* Click the tool icon image:maps/images/tools_icon.png[], and then draw a shape, bounding box, or distance on the map to define the spatial filter.
-* Click *Filter by geometry* in a <<maps-vector-tooltip-locking, locked tooltip>>, and then use the feature's geometry for the spatial filter.
-
 Spatial filters have the following properties:
 
 * *Geometry label* enables you to provide a meaningful name for your spatial filter.
 * *Spatial relation* determines the {ref}/query-dsl-geo-shape-query.html#geo-shape-spatial-relations[spatial relation operator] to use at search time.
-* *Action* specifies whether to apply the filter to the current view or to a drilldown action. Only available when the map is a panel in a {kibana-ref}/dashboard.html[dashboard] with {kibana-ref}/drilldowns.html[drilldowns].
