S3BlobContainer: Revert broadened exception handler again

Catching `Exception` instead of `SdkException` in `copyBlob` and
`executeMultipart` led to failures in `S3RepositoryAnalysisRestIT` due
to the injected exceptions getting wrapped in `IOExceptions` that
prevented them from being caught and handled in `BlobAnalyzeAction`.

Repeat of elastic#126731, regressed due to elastic#126843
Closes elastic#127399
