IconButton missing from website

[praisethemoon]

Icon button is missing and the skill reference needs updating, since the icon property needs to be a JSX and not a literal (so users can use any icon lib).

/// WRONG!
       <IconButton
          icon="add"
          size="sm"
          variant="ghost"
          onClick={openConnectDialog}
          aria-label="New Session"
        />

/// Correct!
        <IconButton
          icon={ <Icon name="add" />}
          size="sm"
          variant="ghost"
          onClick={openConnectDialog}
          aria-label="New Session"
        />
