Add Option to Customize Country List Popup via Custom Class

Description

This PR introduces a new popupContainerClass option to the intl-tel-input library. This option allows developers to specify a custom class for the country list popup container, making it easier to apply scoped styles and avoid conflicts with other parts of the application.

Why This Feature is Needed

• Custom styles can now be applied exclusively to the popup container without affecting other components or plugins.
• Helps avoid conflicts in projects with multiple instances or plugins using older versions of intl-tel-input.

Implementation

• Added popupContainerClass as an optional configuration property.
• Dynamically applies the custom class to the popup container during its creation.

Example Usage

intlTelInput(inputElement, {
  popupContainerClass: 'my-custom-popup-class',
});
