Request body can't be unset

[bourdakos1]

Endpoints with a request body (optional or required) always have an example body prefilled. If this example is deleted, the body is still used in the request/sample code as an empty string.

cURL example on page load:

curl -L -X POST '/v2/store/subscribe' \
--data-raw '{
  "callbackUrl": "https://myserver.com/send/callback/here",
  "eventName": "orderInProgress"
}'

cURL example after deleting code prefilled in editor:

curl -L -X POST '/v2/store/subscribe' \
--data-raw ''

Expected:

curl -L -X POST '/v2/store/subscribe'

Additional feature request:
Since we always provide an example body by default (even when body is optional), it might make sense to remove the + Show optional body and just always show the editor (regardless of optional/required). I believe this would reduce some user confusion of where the body came from on requests where the body was optional.

@simranbentel I think this feature would also fix your issue in #91. Let me know your thoughts 😊
