Open ports using un-deprecated API.

The documentation for `authorizeSecurityGroupIngress` had a typo, or
rather, a formato, that garbled the description of the contents of
the `IpPermissions` map property, so I used the deprecated properties.
This updates the call to `authorizeSecurityGroupIngress` with a correct
`IpPermissions` map property.
