Encoding for body in custom alerting

[egorsmkv]

Describe the feature request

I have the following config:

alerting:
  custom:
    url: "https://webhook.site/80437f67-6027-4d3d-acf8-fd2c26f9e5f6"
    headers:
      "Content-Type": "application/json"
    method: "POST"
    body: |
      {
        "message": "[ALERT_TRIGGERED_OR_RESOLVED]: [ENDPOINT_GROUP] - [ENDPOINT_NAME] - [ALERT_DESCRIPTION] - [RESULT_ERRORS]"
      }

When a trigger executed Gatus send a request:

As you can mention, we have two " here:

It leads to an error on the webhook part (it can't decode the body) so my feature request is to add possibility for it.

confirm. the custom alert will not send valid JSON because of unescaped double quotes within [RESULT_ERRORS] . Of course you can omit this placeholder, but best solution would be to have a JSON serializer finalizing the request body.

edit: Corrected: it is [RESULT_ERRORS] and not ALERT_DESCRIPTION.
