Add one-way binding for Label's Foreground property

Introduced a new binding for the Foreground property of the TextBlock named Label. This binding connects the Foreground property to LabelForeground in the data context, ensuring that changes to LabelForeground are reflected in the TextBlock's foreground color. The binding mode is set to one-way.
