Field Widget Add More

This module adds an option to always show an add more button to the field widget for fields with limited cardinality.

Post-Installation

When configuring form display for a field, an additional option is added to always
show add more button if the field is multiple with limited cardinality. When
this option is checked, the field widget will only show necessary items with
add more button, similar to multiple fields with unlimited cardinality.

The add more button won't be displayed once the items are at the maximum number.
