Hide or cut responseBody when not successful about gatus HOT 1 CLOSED

Fixed by 541e026

While evaluating the prospect of not retaining a service's evaluation result body after the evaluation because it provided no value besides the ability to log it in case of error, I decided to completely remove the response body appended to the logging message when an evaluation wasn't successful.

While the log itself was helpful for debugging, properly leveraging the [BODY] placeholder could also do the same thing without the user having to look at Gatus' logs to debug their applications. Furthermore, the body could be quite lengthy, which means that it may hinder future planned work on supporting longer result history.

TL;DR: The response body is no longer printed in the logs.
