Build: Bump software.amazon.awssdk:bom from 2.42.41 to 2.44.0

[huaxingao]

Supersedes #16273.

The dependabot PR fails CI because the BOM bump cascades to 44 transitive AWS SDK artifact version changes, but the runtime-deps baseline files weren't regenerated. :iceberg-aws-bundle:checkRuntimeDeps then fails build configuration, which transitively fails build-checks, core-tests, and kafka-connect-tests.

This PR makes the same BOM bump and also regenerates the affected runtime-deps baselines:

• aws-bundle/runtime-deps.txt — 44 AWS SDK artifacts bumped to 2.44.0.
• kafka-connect/kafka-connect-runtime/runtime-deps.txt — 39 AWS SDK artifacts bumped to 2.44.0.

Verified locally:

$ ./gradlew :iceberg-aws-bundle:checkRuntimeDeps \
            :iceberg-kafka-connect:iceberg-kafka-connect-runtime:checkRuntimeDeps

BUILD SUCCESSFUL

Same pattern as #16206.

LGTM, but this is a pretty big bump in SDK pov 2 major release, do we know what all precisely went in and are we confident all works

NOTE: There is no integ test against actual AWS for this

Full changelog is here: https://github.com/aws/aws-sdk-java-v2/blob/master/CHANGELOG.md

I don't have an AWS setup to run the integration tests.

I checked 2.44.x & 2.43.x https://github.com/aws/aws-sdk-java-v2/releases/tag/2.43.0 changelogs too it doesn't look concerning to me, yes the integ test would have given confidence, but that true that requires setup lets for now go ahead and merge this if something breaks (since we are not releasing this in 1.11, since branch cut happened), we would be good

Thanks @singhpk234 for the review!
