Update AWS SDK to v3 in Node.js clients

[machafer]

Issue #, if available:

Description of changes: As AWS SDK for JavaScript v2 is in Maintenance Announcement (Phase 2), I propose to update to v3.

• [x] Update code
• [x] Verify modules 1, 2 & 4
• [x] Verify the modules 3 workshop
• [x] Verify the modules 5 & 6 workshop
• [x] Update shell script files
• [x] Remove hugo files

I've spend some time to finally find https://github.com/aws/aws-sdk-js-v3/issues/1877#issuecomment-1071508390 & https://github.com/aws/aws-sdk-js-v3/issues/2282#issuecomment-829297405 due to buffers type changes.

⚠️ Please note that this PR doesn't propose changes for theme-park-frontend which also need to be changed (src/components/IoT.vue)

I also didn't modify moduleXX-script.sh scripts are they yet used?
