Update an existing custom field by slug.
Custom Field Management: Extend your Rackbeat entities with powerful custom fields to capture business-specific information beyond the standard data structure. Available on Premium subscription plans, custom fields support four field types (text, textarea, checkbox, dropdown) and can be applied across products, customers, suppliers, and sales/purchasing documents. These user-defined fields seamlessly integrate with layouts and PDF generation allowing you to tailor Rackbeat to your unique operational requirements while maintaining data consistency throughout your organization.

Note that, if you want to update a dropdown field by adding a new option, then all the previous options should be included in the request buddy. Otherwise the previous options will be deleted and replaced with the new one.
