Description

Follow up to #42687. The workflows endpoint should be able handle both JSON and YAML payloads. As such the admin client should also be capable of handling both types, at least for workflows

Value Proposition

This is a requested capability that workflows must provide, allowing admins to specify their workflows using the format of their choice. YAML utilizes indentation and a more natural, less verbose syntax compared to JSON's reliance on curly braces, square brackets, and double quotes for all strings. It also supports comments.

Goals

Enhance the admin's experience when defining their workflows.
