Upgrade AWS SDK to latest version 2.47.3

[apetrelli]

Type: Upgrade dependency

Please upgrade AWS SDK to the latest version, currently 2.47.3, at least to solve the following CVEs:

• CVE-2026-54399
• CVE-2026-54428

The problems are related to httpcore 4 that is EOL and will never be updated.
Consider that Spring Boot 4.0.x forces httpcore to use the 5.3 branch where those CVEs are not fixed (!)

Hey @apetrelli ,

Thanks on opening the issue.

We have made the AWS SDK dependencies transitive, so you can upgrade to a newer AWS SDK version simply by specifying the desired version in your Maven POM or Gradle build file.

Before each release, we also update the AWS SDK versions to the latest available release.
