Duplicate description for dashboardCardIcon and dashboardCardContentSource

[erikadoyle]

Newly added elements for Viva Connections dashboard card support have duplicate descriptions. Maybe a copypaste error?

"dashboardCardIcon": {
            "type": "object",
            "description": "Represents a configuration for the source of the card’s content",

          ...
        "dashboardCardContentSource": {
            "type": "object",
            "description": "Represents a configuration for the source of the card’s content.",

Suggested description for dashboardCardIcon: Defines the icon properties of a given dashboard card.
