Use python in the custom code action

What changed

EveryCatch custom code actions now support Python. When you add or edit a custom code step, you can choose Python from the language dropdown and write your logic in Python instead of only using the previous options.

This update gives you more flexibility to work with data and APIs in the way you prefer. You can reuse existing Python snippets, handle complex logic more easily, and integrate EveryCatch workflows with external systems using Python libraries that are available in the runtime.
