Results in this function

https://github.com/liquidinvestigations/hoover3/blob/bea9f7ba9a297ed8845dea2650ce254d67fdb6ff/packages/seekstorm-client/src/apis/api_key_api.rs#L67

The function attemps to do serde_json::from_str(&content).map_err(Error::from) on a response marked text/plain, which causes crash (since the json expects to see a quote surrounded string, not a plain string)

Expected output: return Ok(content.to_string()) instead of attempting json parse of text/plain response

Steps to reproduce

Nothing about text/plain vs. json confusion
