Update CardView grid navigation

[LFDanLu]

🙋 Feature Request

#2328 doesn't quite fit for CardView so we'll need to settle on a different keyboard navigation strategy. For now we will discourage having focusable items within a Card in favor of a external action bar so do the following:

• remove the action menu from the CardView stories
• make the checkbox in the Card non-keyboard navigable

This maybe enough to have a satisfactory keyboard navigation experience for CardView for now, make sure to test

🤔 Expected Behavior

Arrow key navigation should move focus between Cards in a CardView

😯 Current Behavior

Right arrow key navigation currently moves focus within a Card in CardView

💁 Possible Solution

See above
