Problem

When a prompt is using angle brackets, they are no longer shown in the UI after saving the prompt in the prompt management. And when such a prompt is used on a language resource with RAG, no custom prompt at all will be sent to LLM.

Steps to reproduce

Create a prompt in the prompt management:
"Words like <this> should be kept in angle brackets."

Go tot an LLM resource which already uses some custom prompts and add the new one to it. 

Translate a sample text in the test window and look at the "Raw data".

No custom prompt is used at all.
