docs: add missing Arg tag to --stderr

Prior to this change the required argument was not shown.

curl.1 before: --stderr
curl.1 after: --stderr <file>

curl --help before:
     --stderr        Where to redirect stderr

curl --help after:
     --stderr <file>  Where to redirect stderr

Closes https://github.com/curl/curl/pull/6692
