Added scroll-into-view behaviour for inline image selector

Browse Source 
refs https://github.com/TryGhost/Team/issues/1225

- added `scrollToCard` action to `koenig-editor` and passed it through to all card components curried to already include the card as an argument
  - action selects the card which places the cursor on it, then triggers our existing cursor scroll-into-view behaviour with an option to allow scrolling a card into view
- updated our cursor scroll-into-view behaviour so if the cursor is large (eg, when it covers a card's height) we make sure the top of the cursor is kept in view rather than the bottom
  - ensures that on small-height screens, opening the gif selector doesn't result in it's search bar being scrolled off screen
