Automatically fill in the Curl webhook

1. We have exploits which use CURL like this https://github.com/bee-san/pyWhat/blob/main/pywhat/Data/regex.json#L137
2. `curl -s -X POST -H \"Content-type: application/json\" -d '{\"text\":\"\"}' \"SLACK_WEBOOK_URL_HERE\"`
3. Where it says `SLACK_WEBOOK_URL_HERE` automatically fill in the webhook (provided because the regex found it)
