Add devfile information section to workspace list card with external link

MR: Pending

Description

As part of our new designs for Workspaces, we need to add the devfile information to the expanded workspace cards so that users can quickly view and access the devfile configuration that defines their workspace setup.

Visual Changes

Acceptance criteria

• Add devfile information section to expanded workspace cards
• External link opens the devfile in a new tab with proper security attributes (rel="noopener noreferrer")
• Handle cases where devfile URL is unavailable gracefully (link to default devfile)
