CURLOPT_POSTFIELDS.3: fix incorrect C string escape in example

- Escape inner quotes with two backslashes.

Two backslashes escapes the backslash for the man page and will show as
a single backslash.

eg: "{\\"name\\": \\"daniel\\"}" shows as "{\"name\": \"daniel\"}".

Closes https://github.com/curl/curl/pull/12588
