[Bug]: HTTP Requests should escape templates values

### DO NOT REPORT VULNERABILITIES HERE! - [x] By checking this box I am confirming this issue is NOT a vulnerability. ### Is there an existing issue for this? - [x] I have searched the existing issues ### What happened? Hello! I’ve identified a minor bug - when a templates value (such as ‘[/chain_description]’) is used in a HTTP Request plugin job, the value isn’t escaped. Characters like ‘“‘ ideally should be automatically escaped to ensure that the JSON remains valid. Would this be possible to implement?
