Expand docs - How to extract fields with varying names (pattern)

Add an example to the docs that highlights this search pattern:

```
 | jmespath output=NewDisplayName "ExtendedProperties[?Name=='targetUpdatedProperties'].Value | from_string(@[0]) | [?ends_with(Name,'.DisplayName')].NewValue"
```
