[PM-11712] Fix scroll going back to focus when scrolling and dismissing the keyboard

PM-11712

📔 Objective

Given the previous fix #1292 the scroll was behaving incorrectly and scrolling back to the field focused when scrolling away from such field causing a lot of confusion. So this PR fixes it by removing the KeyboardResponder and setting the scrollContentMargins constantly instead of depending on whether the keyboard is shown which has a better UX given that the animation doesn't jump and fixes the aforementioned issue.
