A11y Grid | Rendering and Ordering

We did not find a ticket in the Pull Request body,

Phase 1 of the accessible grid component. Implements a similar strategy to the filter component where the grid-cell elements are not rendered but instead act as the data model. This way, developers can map over an array of item and the grid will order them into the semantically accessible reading order.

Functional Testing (Demo QA)

• Items that are added to the grid in a bad order are corrected by the grid
• Screen reader properly identifies the grid label on scan
• Screen reader reads out the content of the cells, and the row and column position
• Alt navigation allows the screen reader to move through the grid in all dimensions
