GEODE-10465: Add ignored exception for Gateway Sender remote locator connection error

The SeveralGatewayReceiversWithSamePortAndHostnameForSendersTest was failing with a fatal error "GatewaySender ln could not get remote locator information for remote site 2". This is a known transient timing issue that occurs when gateway senders attempt to connect to remote locators during test setup before the remote locators are fully available.

Added IgnoredException for "could not get remote locator information for remote site" in the createGatewaySender method to handle this expected transient error, consistent with the pattern used by other WAN tests in the codebase.

This allows the gateway sender to eventually establish the connection once the remote locators are ready, while preventing test failures due to expected startup timing issues.
