Problem to solve

Currently, we're using the SelectableCardSolid component in multiple areas in the dashboard like the Editor, Workspaces, etc.

While the options for Editor and Workspaces will grow over time, they will always remain finite. See #7751 and #12708.

However, this card component can not scale well after adding too many options, especially when the card will have to contain multiple rows of information like the Workspaces (class) selection.

Proposal

Introduce a new, more flexible component or pattern like a dropdown that is able to scale better for selecting from a range of options like the Editor and Workspaces.`

Replace the editor selection cards with the new dropdown component used in the start with options new workspace modal.
