`curl_translate()` should deparse a JSON body

[mgirlich]

httr2::curl_translate(r"--{curl http://example.com --data-raw '{"a": 1, "b": "text"}'  -H Content-Type:application/json}--")

generates

request("http://example.com") %>% 
  req_body_raw("{\"a\": 1, \"b\": \"text\"}", "application/json") %>% 
  req_perform()

it would be much nicer to instead generate

request("http://example.com") %>% 
  req_body_json(list(a = 1L, b = "text")) %>%
  req_perform()

That would be nice, although you'd need to double check that reparsing that yielded the same JSON (since the json roundtrip isn't 100%).

Can use jsonlite::minify for that.
