Improve DateField Validation Labels and Behavior

[hyyan]

Rename the “Maximum” and “Minimum” section in the DateField component to “Min and Max Value” for better clarity. Update the phrasing and explain the functionality as follows:

• For setMax: If the value entered into the component is later than the specified maximum date, the component will fail constraint validation. When both the min and max values are set, the max value must be a date that is the same as or later than the min value.
• For setMin: If the value entered into the component is earlier than the specified minimum date, the component will fail constraint validation. When both the min and max values are set, the min value must be a date that is the same as or earlier than the max value.
