feat(FormItem): Replace `SetFormAttributes` with `SetAttributes` 

BREAKING CHANGE:
`SetFormAttributes` has been removed. To migrate your project, use `SetAttributes` which expects any combination of attribute setters.
Example:
`formItem.SetAttributes(cview.WithLabelWidth(10), cview.WithLabelColor(tcell.ColorYellow))`
or
`formItem.SetAttributes(cview.WithBackgroundColor(tcell.ColorBlack))`
