Fix $ ./setup_test_instance.sh rm: cannot remove '/home/sg/els/eliatra-opensearch-plugin/plugin/target/releases/*': No such file or directory

rm: cannot remove '/home/sg/els/eliatra-opensearch-plugin/plugin/target/releases/*': No such file or directory
This command should not fail if the directories do not exist.
