[FEATURE] Add response property for phase_took

[karinehovhannisyan]

Is your feature request related to a problem?

Hi. After the feature to add support for the phase_took parameter, when enabled, it is not possible to use the returned data as it is not part of the SearchResponse model thus the request param is unusable.

What solution would you like?

Add phaseTook property to the search response model similar to the one in REST high-level client (ref)

What alternatives have you considered?

N/A

Do you have any additional context?
