Issue comments:
Implement sorting by: name, connect, type and status.
Sorting by Name, Connect, Type, Plugin, Status implemented.

Pull request review comments:
Can we use existing `NewTable/TagCell` component?
```suggestion
const TopicsCell: React.FC<CellContext<FullConnectorInfo, unknown>> = ({
```
useMemo is redundant here
```suggestion
 if (!tasksCount) {
    return null;
  }
  
  return (tasksCount ? 
    <>
      {tasksCount - (failedTasksCount || 0)} of {tasksCount}
    </>
  );
```
Pls use styled components attr to change link color. Or update Tag styles to show link correctly
