[DOCS] Correct inline shape snippets in shape query docs (#49921)
[DOCS] Correct inline shape snippets in shape query docs (#49921)

In the shape query docs, the index mapping snippet uses the "geometry"
shape field mapping. However, the doc index snippet uses the "location"
property.

This changes the "location" property to "geometry". It also adds a
comment containing the search result snippet. This should prevent
similar issues in the future.
