Taxonomy proportion Radio/Checkbox widget

The Taxonomy Proportion module requires a widget to allow users to select a taxonomy term using a radio or checkbox selection method and input a proportion (%) value.

Create a custom widget for Taxonomy Proportion that provides a radio or checkbox feature for taxonomy term selection, along with a percentage input field (0-100%).

Remaining tasks

• Implement the radio/checkbox widget for term selection.
• Ensure the proportion field correctly validates input values.

This is part of updating functionality from Drupal 7 to Drupal 10/11.
