build(deps): bump aws-sdk-java-v2 to 2.19.26

[iwasakims]

What this PR changes/adds

bump the version of aws-sdk-java-v2 to 2.19.26 which supports virtual-hosted style URL with endpoint override.

Why it does that

as a prerequisite of eclipse-edc/Technology-Aws#28

Further notes

Existing S3 tests of Connector passed against 2.19.26. (I needed to modify dependencyResolutionManagement of settings.gradle.kts to make edc-versions picked from local Maven repo.)
