Add ability to see the tile counts with a hyperlink inside the floor plan detail view

[tsm1th]

Environment

• Nautobot version: 2.0.5
• nautobot-floor-plan version: 2.0.0

Proposed Functionality

Ability to see how many children exists for a given floor plan and a link to access them

Use Case

There is no good way to access the "floor plan tile" view and this would allow access via the parent's detail page. The count and hyperlink will be available via the "Children" field.
