Upgrade AWS Java SDK to 2.31.78 (#131050) (#131354)

This picks up the fix for the locale bug reported at aws/aws-sdk-java-v2#5968. This reverts the patching of the library added in commit 2697a3a, except for the test enhancement. Fix confirmed in e.g. locale `ar-ER` with ./gradlew ":plugins:discovery-ec2:test" \ --tests "org.elasticsearch.discovery.ec2.Ec2DiscoveryTests.testFilterByTags" \ -Dtests.seed=596874EED28A2B92 -Dtests.locale=ar-ER -Dtests.timezone=NET \ -Druntime.java=24
