fix(stark-ui): change default behaviour of collapsible icon

BREAKING CHANGES:

Collapsible component:
  - `iconSpinningEnabled` Input has been removed. The spin effect can be
  done easily by the developer if needed
  - The default icon is now 'chevron-right' and it is rotated 90
  degrees when collapsible is expanded.
