Add Label component

**Is your feature request related to a problem? Please describe.**
Since we already have TextInput, Checkbox, and almost all the Form components, we need also to add a new `Label` component to be used with the `TextInput`

**Describe the solution you'd like**
Adding new `Label` component to be used with Forms components.

**Describe alternatives you've considered**
Manually adding `Text` component with custom styles.

**Additional context**
Adding new `Label` component makes it much easier to deal with forms.

Start by reviewing the existing TextInput, Checkbox, and other Form components to understand their structure and usage patterns. Define the Label component's expected API and styling from those components, then verify that it can be used with form components as requested.
