Small type in docs for rclone serve s3

"For details see the rclone serve s3 documentation."

the url is not correct, points to https://rclone.org/commands/rclone_serve_http

it should point to https://rclone.org/commands/rclone_serve_s3/

Just submit a PR to fix it. No need to post :slight_smile:

small things like this can be fixed by hitting edit in github web - no need for any git cmd.
