Improve Queue Card Accessibility

[bhuvy2]

Problem Currently navigating Queue Cards are opaque. Landmarks and sections should be introduced so navigating a card with a screen reader makes sense. Below is an example image with firefox's Accessibility monitor

Acceptance Criteria

• The highlighted section attribute should have a top level name like card-container
• The immediate child should actually be the card
• The text container containing CS 101 should have a title like Queue Title
• The node containing Lab & Discussion Should have a Queue Type Title
• The node containing location should be split up into two nodes, one with the location with the title Location and another with Number of questions containing number of questions.

Naturally if anyone wants to alter the actual English wording of anything I proposed, feel free to. Relates to #135
