Nate Hunzaker 4a807761a4 Prevent okhttp from adding ;charset=utf8 to ContentType Header (#23580 )

Summary:
Before this commit, `fetch()` calls append `"charset=utf8"` to the `Content-Type` header on Android (and not on iOS). This is because of an implementation detail in the okhttp library. This means that you can make a call on the JavaScript side like:

```javascript
let body = JSON.stringify({ key: "value" });

let headers = {
  "Content-Type": "application/json"
};

fetch("http://10.0.2.2:3000", { method: "POST", body, headers });
```

However the resulting request appends the utf8 character:

```
POST - 13:34:32:
  content-type: application/json; charset=utf-8
  content-length: 15
  host: 10.0.2.2:3000
  connection: Keep-Alive
  accept-encoding: gzip
  user-agent: okhttp/3.12.1
```

Passing byte array into the RequestBody avoids this, as recommended by a maintainer of okhttp:
