Pull Request Overview

This PR ensures that when versioning is disabled, the ListObjectVersions API always returns isLatest = true. It updates the factory method, adjusts the integration test to assert the new flag, and records the change in the changelog.

• ObjectVersion.from(S3Object) now unconditionally sets isLatest to true and includes a brief JavaDoc.
• Integration test ListObjectVersionsIT updated to extract and assert the new isLatest property.
• CHANGELOG.md updated with the new 4.5.1 entry detailing the fix and dependency bumps.

• [nitpick] Consider expanding the Javadoc for the from(S3Object) overload to include @param tags for each argument and explicitly note that isLatest is always true when versioning is disabled.

• [nitpick] Consider adding a focused unit test for ObjectVersion.from(S3Object) to verify at the unit level that isLatest is set to true when versioning is disabled, complementing this integration test.
