Jira ticket Github issue

:bulb: Description

The custom built FindInPageBar had functionality to pre-populate the search field from the long press “Find in page” option when a user highlights text on a webpage. The new UIFindInteractor used to fix FXIOS-8693 did not behave the same. This PR restores that functionality.
