feat: allow header to move down on pull to refresh on iOS

[andreialecu]

This implements a new property:

  /**
   * Whether the header moves down during overscrolling (for example on pull-to-refresh on iOS) or sticks to the top
   *
   * @default false
   */
  allowHeaderOverscroll: boolean

It basically allows the header to move down while overscrolling on iOS so that the pull to refresh appears above the header rather than below.

Here's a video of what this does:
