AWS SDK deprecation

[johnseekins-pathccm]

Similar to #535, I'm seeing the following message in my execution logs. Any chance we can upgrade the SDK version?

(node:1669) NOTE: The AWS SDK for JavaScript (v2) will enter maintenance mode
on September 8, 2024 and reach end-of-support on September 8, 2025.

Please migrate your code to use AWS SDK for JavaScript (v3).

Fixed as part of #529. This upgrade will be included in the next release.
